Express each of the following with rational denominator

Answer 1

$Given : \frac{b^2}{ \sqrt{a^2 + b^2} + a}$

$= \ \textgreater \ \frac{b^2( \sqrt{a^2 + b^2} - a) }{( \sqrt{a^2 + b^2 } + a)( \sqrt{a^2 + b^2} - a) }$

$= \ \textgreater \ \frac{b^2( \sqrt{a^2 + b^2} - a) }{ (\sqrt{a^2 + b^2})^2 - a^2 }$

$= \ \textgreater \ \frac{b^2( \sqrt{a^2 + b^2} - a) }{a^2 + b^2 - a^2}$

$= \ \textgreater \ \frac{b^2( \sqrt{a^2 + b^2} - a)}{b^2}$

$= \ \textgreater \ \sqrt{a^2 + b^2} - a$
