Question

$hey \: plz \: solve \: this \\ it \:is \: chapter \: \: rationalisation$
​

Answer 1

$given \\ \\ = \frac{b {}^{2} }{ \sqrt{a {}^{2} + b {}^{2} } + a } \: \\ \\ \boxed{ \green{step \: by \: step \: explanation}} \\ \\ = \frac{b {}^{2} }{ \sqrt{a {}^{2} + b {}^{2} } + a} \times \: \frac{ \sqrt{a {}^{2} + b {}^{2} } - a }{ \sqrt{a {}^{2} + b {}^{2} } - a } \\ \\ = \frac{b {}^{2} ( \sqrt{a {}^{2} + b {}^{2} } - a )}{a {}^{2} + b { }^{2} - a}$
