Question

calcule usando as propriedades da potencicação $(\frac{2}{3})² . (\frac{2}{3})²$

Answer 1

$\left(\dfrac{2}{3}\right)^2 \times \left(\dfrac{2}{3}\right)^2 =\left(\dfrac{2^2}{3^2}\right) \times \left(\dfrac{2^2}{3^2}\right)\\ =\left(\dfrac{4}{9}\right) \times \left(\dfrac{4}{9}\right) =\left(\dfrac{4 \times 4}{9 \times 9}\right) =\boxed{\dfrac{16}{81}\right}$

Bons estudos!
