Question

Qual o valor de (4/-2)³ -4.(-1/0,5)² - (-2.4/4)³ ?

Answer 1

(4/-2)³ = (4/-2)*(4/-2)*(4/-2) = -8

(-1/0,5)² = (-1/0,5)*(-1/0,5) = 4

(-2*4/4)³ = (-8/4)*(-8/4)*(-8/4) = -8

(-8) * -4 * 4 - (-8) =  -8 -16 + 8 = -16

Answer 2

$Resolu\c{c}\~ao \to \left\{\begin{array}{ccc}(\frac{4}{-2})^3-4*(\frac{-1}{0,5})^2-(-2*\frac{4}{4})=\\\\\frac{4^3}{(-2)^3}-4*(\frac{(-1)^2}{0,5^2})-(-2*1) = \\\\\frac{64}{-8}-4*(\frac{1}{0,25})-(-2) = \\\\-8-\frac{4}{0,25}+2 = \\\\-8 -\frac{4}{\frac{1}{4}}+2 = \\\\-8-4*4+2 = \\\\-8-16+2 =\\\\ \boxed{\boxed{-22}}\end{array}\right$

Espero ter ajudado. =^.^=
