Question

ratinalizing factor of (√a + √b) =??​

Answer 1

$\huge \boxed{ \bold{Answer}}$

The rationsaling factor of (√a+√b) is (√a-√b)

proof:

=(√a + √b)

=(√a+√b)(√a-√b)

=(√a)²-(√b)²

=$\bold{{a}^{2\times\frac{1}{2}} - {b}^{2\times\frac{1}{2}}}$

=a-b

Let a=5 and b=3.

=>5-3=2

So 2 is a real number and hence verified because rationsaling means multiplying a irrational number with a irrational so that it's gives a rational which in case (√a-√b) is here.
