Answer 2

$\displaystyle{\sf{\frac{b^2}{\sqrt{a^2+b^2}+a } }}\\\\\\\displaystyle{\sf{=\frac{b^2}{\sqrt{a^2+b^2}+a }*\frac{\sqrt{a^2+b^2}-a }{\sqrt{a^2+b^2}-a} }}\\\\\\\displaystyle{\sf{=\frac{b^2(\sqrt{a^2+b^2}-a) }{(\sqrt{a^2+b^2} )^2-(a)^2} }}\\\\\\\displaystyle{\sf{=\frac{b^2(\sqrt{a^2+b^2}-a )}{a^2+b^2-a^2} }}\\\\\\\displaystyle{\sf{=\frac{b^2(\sqrt{a^2+b^2}-a )}{b^2}}}$

$\boxed{\displaystyle{\sf{=\sqrt{a^2+b^2}-a }}}$
