Two classmates Vamsi and Rupa simplified two different expressions during
the revision hour and explained to each other their simplifications.
Vamsi explains simplification of √2
√5+ √3
by rationalising the denominator
and Rupa explains simplifications of (√2 + √3 ) (√2 – √3 ) by using the
identity (a +b) (a – b). Answer the following questions.
By rationalising the denominator of √2
√5 + √3
vamsi got the answer:
a)
√2
√5 − √3
b) √2 ( (√5 − √3 )
2
c) (√5 – √3 ) d) √2 ( (√5 + √3 )
