Question

qual o resultado? cálculos por favor!!

Answer 1

$\ [(5)^3\ - (-11)^1 * ( \sqrt{5})^0 - (-2)^3] * (4^3 * ( \dfrac{1}{4})^{-1})^{-2}$

====

$\ [ 125 - (-11) * 1 - (-8) ] * (16 * 4})^{-2} \\ \\ \\ \ [ 125 +11 + 8 ] * (64})^{-2} \\ \\ \\ \ [ 126 + 8 ] * \dfrac{1}{64^2}$

$144 * \dfrac{1}{64^2} \\ \\ \\ \dfrac{144}{64^2} \\ \\ \\ \dfrac{2^4. 3^2}{2^{12}} \\ \\ \\ \dfrac{3^2}{2^8} =\ \textgreater \ \dfrac{9}{256}$
