Find the simplest rationalising of √5-√2​

Answer»

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,
