సాధన.
100 = 60(1) + 40
60 = 40(1) + 2
40 = 20(2) + 0
కావున 60, 100 ల గ.సా.భా = 20

ప్రశ్న 2.

ప్రశ్న 3.
\(\frac{36}{99}\)ని దశాంశ సంఖ్యగా వ్రాయుము.
సాధన.
\(\frac{36}{99}=\frac{4 \times 9}{9 \times 11}=\frac{4}{11}=0 . \overline{36}\)

ప్రశ్న 4.
log \(\frac{a^{\mathbf{m}^{\mathbf{n}}} \mathbf{b}^{\mathbf{z}}}{\mathbf{c}^{\mathbf{z}}}\) యొక్క విస్తరణ రూపాన్ని రాయండి.
సాధన.
log \(\frac{a^{\mathbf{m}^{\mathbf{n}}} \mathbf{b}^{\mathbf{z}}}{\mathbf{c}^{\mathbf{z}}}\) = log ambn – log cz [∵ log \(\frac{x}{y}\) = log x – log y]
= log am + log bn – log cz [∵ log xy = log x + log y]
= m log a + n log b – z log c.

ప్రశ్న 5.
x2 + y2 = 7xy అయిన log \(\left(\frac{x+y}{3}\right)\) = \(\frac{1}{2}\) (log x + log y) అని నిరూపించుము.
సాధన.
x2 + y2 = 7xy ఇరువైపులా 2xy కలుపగా
x2 + y2 + 2xy = 7xy + 2xy = 9xy
(x + y)2 = 9xy ఇరువైఫులా వర్గమూలం పరిగణించగా.
\(\sqrt{(x+y)^{2}}=\sqrt{9 x y}\)
∴ \(\frac{x+y}{3}\) = 3√xy
⇒ \(\frac{x+y}{3}\) = √xy = (xy)1/2
⇒ \(\frac{x+y}{3}\) = (xy)1/2
ఇరువైపులా సంవర్గమానం పరిగణించగా
log \(\frac{x+y}{3}\) = log (xy)\(\frac{1}{2}\)
= \(\frac{1}{2}\) log(xy)
⇒ log (\(\frac{x+y}{3}\)) = \(\frac{1}{2}\) (log x + log y) అని ఋజువైనది.

AP Board 10th Class Maths Solutions 1st Lesson Important Questions and Answers వాస్తవ సంఖ్యలు

ప్రశ్న 6.
యూక్లిడ్ భాగహార శేషవిధి ఆధారంగా 4830 మరియు 759 యొక్క గ.సా.భా.ను కనుగొనుము.
సాధన.
ఇచ్చిన సంఖ్యలు 4830 మరియు 759
4830 = 759 × 6 + 276
759 = 276 × 2 + 207
276 = 207 × 1 + 69
207 = 69 × 3 + 0
∴ 4830 మరియు 759 ల గ.సా.భా. = 69

ప్రశ్న 7.
1260 మరియు 1440 ల గ.సా.కా. ను యూక్లిడ్ భాగహార న్యాయం ఉపయోగించి కనుక్కోండి. –
సాధన.
ఇచ్చిన సంఖ్యలు 1260, 1440.
1440 = 1260 × 1 + 180
1260 = 180 × 7 + 0 .
∴ 1260, 1440 ల గ.సా.కా. = 180.

ప్రశ్న 8.
x2 + y2 = 10xy అయిన 2 log(x – y) = logx + log y + 3 log 2 అని నిరూపించండి.
సాధన.
x2 + y2 = 10xy
రెండు వైపులా ‘2xy’ ను తీసివేయగా,
x2 + y2 – 2xy = 10xy – 2xy = 8xy
(x – y)2 = 8xy
రెండువైపులా ‘logarithm’ ను తీసుకొనిన
log (x – y)2 = log 8xy = log 8 + log x + log y
⇒ 2 log (x – y) = 3 log 2 + log x + logy.

ప్రశ్న 9.
log10 5 కరణీయ సంఖ్యా ? అకరణీయ సంఖ్యా ? నీ జవాబును సమర్థించుము.
సాధన.
log10 5 = x అనుకొనిన
10x = 5
కాని 5 ను ‘x’ యొక్క ఏ విలువకు 10x రూపంలో వ్రాయలేము.
∴ log10 5 ఒక అకరణీయ సంఖ్య.

ప్రశ్న 10.
1.2333333……. ను \(\frac{p}{q}\) రూపంలో వ్రాయుము. (p మరియు q లు సాపేక్ష ప్రధానాంకాలు)
సాధన.
x = 1.2333333 అనుకొనుము. = 1.23
= 1.2 + 0.03 + 0.003 + 0.0003 + …………
= 1.2 + \(\frac{3}{10^{2}}+\frac{3}{10^{3}}+\frac{3}{10^{4}}\) + …………….
= 1.2 + \(\frac{-\frac{3}{10^{2}}}{1-\frac{1}{10}}\)
= 1.2 + \(\frac{1}{30}\) = \(\frac{37}{30}\)

ప్రశ్న 11.
√5 + √7 అనేది ఒక కరణీయ సంఖ్య అని నిరూపించుము.
సాధన.
√5 + √7 ను ముందుగా కరణీయ సంఖ్య కాదు అనుకుందాం.
దీనిని విరుత ద్వారా నిరూపిద్దాం.
∴ √5 + √7 = a అనుకుందాం. (∵ a ఒక అకరణీయ సంఖ్య)
⇒ √7 = a – √5 ఇరువైపులా వర్గం చేయగా
(√7)2 = (a – √5)
⇒ 7 = a2 + 5 – 2a√5
⇒ 2a√5 = a2 + 5 – 7 = a2 – 2
⇒ √5 = \(\frac{a^{2}-2}{2 a}\)
దీని యందు L.H.S భాగం √5 ఒక అకరణీయ సంఖ్య.
RHS భాగం నందు గల \(\frac{a^{2}-2}{2 a}\) అనునది ఒక అకరణీయ సంఖ్య ఎదుకనగా ‘a’ ఒక అకరణీయ సంఖ్య కావున.
√5 = \(\frac{a^{2}-2}{2 a}\) సత్యం కావలెనన్న ఒక కరణీయ సంఖ్య (√5) ఒక ఆకరణీయ సంఖ్య (\(\frac{a^{2}-2}{2 a}\)) కు
సమానం కావలెను. కాని ఇది అసాధ్యం.
కావున మనం తీసుకున్నట్లు √5 + √7 అనునది అకరణీయ సంఖ్య అగుట అసాధ్యం.
కావున √5 + √7 ఒక కరణీయ సంఖ్య అని ఋజువైనది.

AP Board 10th Class Maths Solutions 1st Lesson Important Questions and Answers వాస్తవ సంఖ్యలు

ప్రశ్న 12.
√5 + √11 ను కరణీయ సంఖ్య అని నిరూపించండి.
సాధన.
√5 + √11 అనేది ఒక అకరణీయ సంఖ్య అని ఊహించండి.
√5 + √11 = 2, ఇందు a, b లు పరస్పర ప్రధానాంకాలు మరియు b ≠ 0
∴ √5 = \(\frac{a}{b}\) – 11
ఇరువైపులా వర్గం చేయగా
√5 = \(\frac{\mathrm{a}^{2}}{\mathrm{~b}^{2}}+11-2 \frac{\mathrm{a}}{\mathrm{b}} \sqrt{11}\)

\(2 \frac{a}{b} \sqrt{11}=\frac{a^{2}}{b^{2}}+11-5=\frac{a^{2}}{b^{2}}+6\)

√11 = \(\frac{a^{2}+6 b^{2}}{b^{2}} \times \frac{b}{2 a}=\frac{a^{2}+6 b^{2}}{2 a b}\)

a, b లు పూర్ణసంఖ్యలు కావున \(\frac{a^{2}+6 b^{2}}{2 a b}\) అకరణీయ సంఖ్య.
కావున √11 ఒక అకరణీయ సంఖ్య. ఇది √11 కరణీయ సంఖ్య అనేదానికి విరుద్ధం.
∴ √5 + √11 ఒక కరణీయ సంఖ్య.

ప్రశ్న 13.
√3 ను కరణీయ సంఖ్య అని నిరూపించండి.
సాధన.
√3 ఒక అకరణీయ సంఖ్య అనుకొనుము.
√3 = \(\frac{a}{b}\) అయ్యే విధంగా a, b లు పరస్పర ప్రధాన సంఖ్యలు మరియు b ≠ 0
⇒ b√3 = a ఇరువైపులా వర్గం చేయగా
3b2 = a2
a2 ను 3 భాగించును, a ను కూడా 3 భాగించును.
a = 3c అయ్యే విధంగా c ఒక పూర్ణ సంఖ్య
⇒ a2 = 9c2
⇒ 3b2 = 9c2 (a2 = 3b2)
⇒ b2 = 3c2

మనం నిరూపించవలసిన భావనకు విరుద్ధంగా 2 + 5√3 ఒక అకరణీయ సంఖ్యగా ఊహించు కుందాం.
⇒ 2 + 5√3 = \(\frac{a}{b}\) అయ్యే విధముగా a, b లు పరస్పర ప్రధాన సంఖ్యలు, b ≠ 0
⇒ 5√3 = \(\frac{a}{b}\) – 2
⇒ √3 = \(\frac{a}{5 b}-\frac{2}{5}\)
ఇందులో RHS నందు
\(\frac{a}{5 b}\), \(\frac{2}{5}\)∈ Q

My chicken listens to my stories; she has other uses too. If you play with her and take her mind off what’s going on, you can quickly – very quickly snatch a feather or two when she is distracted.

4. Write a story using the following hints.

Hints: An old tiger – weak – unable to catch its prey – thinks of a plan – wants to draw his prey closer – showing a golden bangle – bait – a poor man – comes – the other side of the river – about to drink water – hears someone calls – sees the tiger – afraid – tries to run away – tiger’s call – great scholar – changed – sorry for sins – now a pious – accept the golden ring – poor man – sees the golden bangle – becomes greedy – greediness overcomes – fear – goes close to tiger – to accept the ring – tiger spring up – kill – eat.
Answer:
Once there was on old tiger. He was week. He was unable to catch his prey. So he thought of a plan. He wanted to draw his prey closer to him by showing the golden bangle as a bait

One day a poor man came that way. He was on the other side of the river. When he was about to drink water, he heard someone calling him. He looked up and saw the tiger on the other side of the river. At first the poor man was afraid. He tried to run away from there. At the same time he heard the tiger’s call again “Oh! great scholar, I don’t harm you. I am now a changed one. I am sorry for my sins. I am now a pious man ! Please accept golden ring and help me to recede my sins.”

When the poor man saw the golden bangle, he became greedy. His greediness overcame his fear. He believed the tiger’s words. So he went close to the tiger to accept the golden ring. At once the tiger sprang upon him, killed him and ate him.

This story tells us “Greediness brings us misery”.

6. In the lesson ‘Painted House, Friendly Chicken and Me’, you have learnt that Thandi sometimes goes to the city along with the members of her family. One day she went to the city along with her mother, sisters and aunts and returned to the village.
Imagine you are Thandi and describe your feelings about city people, houses, etc. in the form of a diary entry.
Answer:
24th July, 2021,
9.00 pm.
Dear Diary,

Today I went to the city with my mother, sisters and aunts in a wagon pulled by four mules. I enjoyed the journey a lot. Visiting the city with the members of my family gives me immense joy. There are tall buildings and wide roads in the city. All the houses there are in one sad colour. But our painted houses are very beautiful to look at. There I found no much greenery either. Here, our village and the surroundings have rich greenery with number of trees. The city people stared at my mother and relatives because the city folk have nothing so good as the Ndebele women. I am always happy to see the city people stare at us. The Ndebele women wear best blankets, best neck rings and very good leg rings, of course. But the city women have no beads at all. I feel sorry for them and I give them a good smile. Next time when I go to the city, I shall give them beaded aprons and beaded fringed lion flaps made by me. I think they will be very happy then.

Thandi
