Important Definition RD Sharma Chapter 3 Class 9 Maths Exercise 3.1 Solutions
Find some examples of Rationalisation based on the identities mentioned above-
Ques 1-(4 + √7) (3 + √2)
Solution- (4 + √7) (3 + √2)
= 12 + 4√2 + 3√7 + √14
Ques 2- (3 + √3) (5- √2 )
Solution- (3 + √3) (5- √2 )
= 15 – 3√2 + 5√3 – √6
Ques 3- (√5– 2) (√3 – √5)
Solution- (√5– 2) (√3 – √5)
= √15 – √25 – 2√3 + 2√5
= √15 – 5 – 2√3 + 2√5
Ques 4- (11 + √11) (11 – √11)
Solution- (11 + √11) (11 – √11)
= 11² – (√11)²
= 121 – 11 = 110
Ques 5- (2√5 + 3√2)²
Solution- (2√5 + 3√2)²
= 2√5² + 3√2² + 2(2√5) (3√2)
= 20 + 18 + 12√10
= 38 + 12√10
