Answer : √15 - √10

Answer 1

Hi there !

__________________________

​

Given :

√5 / √3 + √2

Solution :

√5 / √3 + √2

multiply numerator and denominator by √3 - √2.

As follows :)

√5 / √3 + √2 × √3 - √2 / √3 - √2

√5 ( √3 - √2) / (√3)² - (√2)²

√15 - √10 / 3 - 2

√15 - √10

Hence,

On rationalising it's denominator, we get ;

=> √15 - √10

Thanks for the question !

Answer 2

Heya!!

= √5/ (√3 +√2)

= √5/ (√3 +√2) × (√3 -√2)/(√3 -√2)

= √5 ( √3 -√2) / (√3^2 - √2^2)

= √5 ( √3 -√2) / 3-2

= √5 ( √3 -√2)

Or

√15 -√10

Hope it helps uh!!
