RD Sharma Class 9 Chapter 2 Exponents of Real Numbers Ex 2.1

(i) 3(a4 b3)10 x 5 (a2 b2)3

(ii) (2x -2 y3)3

RD Sharma Solutions Class 9 Chapter 2 Solutions” src=”https://cdn1.byjus.com/wp-content/uploads/2019/10/rd-sharma-class-9-chapter-2-exponents-of-real-numb.png” alt=”RD Sharma Class 9 Chapter 2 Exponents of Real Numbers Ex 2.1 Question 1″ />

Solution:

Using laws: (am)n = amn , a0 = 1, a-m = 1/a and am x an = am+n]

(i) 3(a4 b3)10 x 5 (a2 b2)3

On simplifying the given equation, we get;

= 3(a40 b30) x 5 (a6 b6)

= 15 (a46 b36)

[using laws: (am)n = amn and am x an = am+n]

यहाँ important point यह है कि हमने पहले power rule apply किया, फिर multiplication rule का use किया। यह approach board exams में marks लाने के लिए जरूरी है।

(ii) (2x -2 y3)3

On simplifying the given equation, we get;

= (23 x -2 × 3 y3×3)

= 8 x -6 y9

Negative exponents को handle करना tricky हो सकता है। यहाँ x-6 को 1/x6 के रूप में भी लिख सकते हैं।

Question 2: If a = 3 and b =-2, find the values of:

(i) aa+ bb

(ii) ab + ba

(iii) (a+b)ab

Solution:

(i) aa+ bb

Now putting the values of ‘a’ and ‘b’, we get;

= 33 + (−2)−2

= 33 + (−1/2)2

= 27 + 1/4

= 109/4

यह question negative exponents के साथ calculation practice करने के लिए है। (−2)−2 = 1/(−2)2 = 1/4 याद रखें।

(ii) ab + ba

Now putting the values of ‘a’ and ‘b’, we get;

= 3−2 + (−2)3

= (1/3)2 + (−2)3

= 1/9 – 8

= −71/9

(iii) (a+b)ab

Now putting the values of ‘a’ and ‘b’, we get;

= (3 + (−2))3(−2)

= (3–2))−6

= 1−6

= 1

यहाँ एक interesting fact है – किसी भी number की power 1 हमेशा 1 होती है, चाहे exponent कुछ भी हो।

Question 3: Prove that

RD Sharma Class 9 Chapter 2 Maths Ex 2.1 Question 3

Solution:

(i) L.H.S. =

RD Sharma Class 9 Chapter 2 Maths Ex 2.1 Question 3 solution

= R.H.S.

Proof questions में LHS और RHS को separately solve करना चाहिए। यह method board exams में full marks दिलाता है।

(ii) We have to prove here;

L.H.S. =

RD Sharma Class 9 Chapter 2 Maths Ex 2.1 Question 3 solution

=R.H.S.

(iii) L.H.S. =

RD Sharma Class 9 Chapter 2 Maths Ex 2.1 Question 3 solution

Question 4: Prove that

RD Sharma Class 9 Chapter 2 Maths Ex 2.1 Question 4

Solution:

(i) L.H.S

RD Sharma Class 9 Chapter 2 Maths Ex 2.1 Question 4 solution

= R.H.S.

(ii) L.H.S

RD Sharma Class 9 Chapter 2 Maths Ex 2.1 Question 4 solution

= R.H.S.

इस type के questions में algebraic manipulation की practice होती है। यह advanced level के questions के लिए foundation बनाता है।

Question 5: Prove that

RD Sharma Class 9 Chapter 2 Maths Ex 2.1 Question 5

Solution:

(i) L.H.S.

RD Sharma Class 9 Chapter 2 Maths Ex 2.1 Question 5 solution

= R.H.S.

(ii)

L.H.S.

RD Sharma Class 9 Chapter 2 Maths Ex 2.1 Question 5 solution

= R.H.S.

Question 6: If abc = 1, show that

RD Sharma Class 9 Chapter 2 Maths Ex 2.1 Question 6

Solution:

RD Sharma Class 9 Chapter 2 Maths Ex 2.1 Question 6 solution

यह question conditional proof का example है। Given condition abc = 1 को effectively use करना होता है। यह type के questions Class 10 में भी आते हैं।
