Question

Calcule as potencias (-3/4 m)²

Answer 1

Explicação passo-a-passo:

Temos que:

$\sf \left(-\dfrac{3m}{4}\right)^2=\left(-\dfrac{3m}{4}\right)\cdot\left(-\dfrac{3m}{4}\right)$

$\sf \left(-\dfrac{3m}{4}\right)^2=\red{\dfrac{9m^2}{16}}$

Answer 2

Oie, Td Bom?!

$= ( - \frac{3}{4} m) {}^{2}$

$= ( - \frac{3}{4} ) {}^{2} \: . \: m {}^{2}$

$= \frac{9}{16} m {}^{2}$
