Question

РЕШИТЕ ПРИМЕР!!!!!!!

Answer 1

$=frac{frac{(sqrt{a})^{3}+(sqrt{b})^{3}}{sqrt{a}+sqrt{b}} }{a-b}+frac{2sqrt{b}}{sqrt{a}+sqrt{b}}-frac{sqrt{ab} }{a-b} =frac{frac{(sqrt{a}+sqrt{b})(a-sqrt{ab}+b)}{sqrt{a}+sqrt{b}} }{a-b}+frac{2sqrt{b} }{sqrt{a}+sqrt{b}}-frac{sqrt{ab} }{a-b}=frac{a-sqrt{ab}+b }{(sqrt{a}-sqrt{b})(sqrt{a}+sqrt{b})}+frac{2sqrt{b} }{sqrt{a}+sqrt{b}}-frac{sqrt{ab} }{(sqrt{a}-sqrt{b})(sqrt{a}+sqrt{b})}=frac{a-sqrt{ab}+b+2sqrt{ab}-2b-sqrt{ab}}{a-b}=frac{a-b}{a-b}=1$
