Question

(6^√4)^-3 -( 5/√5)^2
Qual o passo a passo da resolução desta expressão?

Answer 1

$\left(6^{\sqrt{4}}\right)^{-3}-\left(\frac{5}{\sqrt{5}}\right)^2\\\\\left(6^{2}\right)^{-3}-\left(\frac{5^2}{\sqrt{5}^2}\right)\\\\\left(6\right)^{2\;.\;-3}-\frac{25}{5}\\\\6^{-6}-5\\\\\left(\frac{1}{6}\right)^6-5\\\\\frac{1^6}{6^6}-5\\\\\frac{1}{46656}-5\\\\Caso\;deixar\;tudo\;na\;mesma\;fracao:\\MMC=46656\\\\\frac{1-46656}{46656}\\\\\frac{-46655}{46656}$
