raiz de a^-1.raiz de a^-1.raiz de a^-1

Answer 1

Oi :) 
$\sqrt{a^{-1}} \sqrt{a^{-1}} \sqrt{a^{-1}}= \\ \\ \sqrt{ \frac{1}{a} }\sqrt{ \frac{1}{a} }\sqrt{ \frac{1}{a} } \\ \\ \frac{\sqrt{ 1}}{ \sqrt{a} } \frac{\sqrt{ 1}}{ \sqrt{a} } \frac{\sqrt{ 1}}{ \sqrt{a} } \\ \\ \frac{1}{ \sqrt{a} } \frac{1}{ \sqrt{a} } \frac{1}{ \sqrt{a} } \\ \\ \frac{1}{a}. \frac{1}{ \sqrt{a} } = \frac{1}{a \sqrt{a} }$ 
ou ainda: 
$\frac{1}{a \sqrt{a} }. \frac{a \sqrt{a} }{a \sqrt{a}} = \frac{a \sqrt{a} }{a^2.a}= \frac{ \sqrt{a} }{a^2}$
