Question

Calcule o valor da expresao (4 sobre 3) elevado a 3 - (-1 sobre 3) elevado a 3 +(3 sobre 2) elevado -2

Answer 1

$( \frac{4}{3} )^3 - (- \frac{1}{3})^3 + ( \frac{2}{3})^-^2 =$
$\frac{64}{27} - (- \frac{1}{27}) + ( \frac{3}{2} )^2=$
$\frac{64}{27} - (- \frac{1}{27}) + \frac{9}{4} =$
$\frac{64}{27} + \frac{1}{27} + \frac{9}{4} =$
$\frac{503}{108}$
