[tex]= \frac{a \sqrt{a}+b \sqrt{b} }{ \sqrt{a}+ \sqrt{b}} . \frac{ \sqrt{a}- \sqrt{b} }{\sqrt{a}- \sqrt{b} } \\ = \frac{a^{2}-a \sqrt{ab}+b \sqrt{ab}-b^{2}}{a-b} \\ = \frac{a^{2}-b^{2}-a \sqrt{ab}+b \sqrt{ab}}{a-b} \\ = \frac{(a+b)(a-b)- \sqrt{ab} (a-b) }{a-b} \\ = a+b- \sqrt{ab} (A) \\ Semoga Membantu [/tex]
