Question

find the simplest rationalising of √5-√2​

Answer 1

Answer:

Rationalising Factor is (√5-√3)

Answer is 2

Step-by-step explanation:

Given,

√5-√2

For Rationalising let us multiply by

√5+√3

So,

(√5-√3)(√5-√3)

(a+b)(a-b)=a^2 - b^2

So,

(√5-√3)(√5-√3) = (√5)^2 - (√3)^2

Here square and root gets cancelled

Remaining,

5-3

=2,
