Question

me ajudemmmmm pfv é para hoje

Answer 1

$\left(\dfrac{4}{5}\right )^2 = \dfrac{4^2}{5^2} = \dfrac{16}{25}\\\\ \dfrac{4^2}{5} = \dfrac{16}{5}\\\\ \left(\dfrac{-3}{10}\right)^2 = \dfrac{-3^2}{10^2} = \dfrac{9}{100}\\\\ \left(\dfrac{-9}{8}\right)^2 = \dfrac{-9^2}{8^2} = \dfrac{81}{64}\\\\ \left(\dfrac{-1}{2}\right)^5 = \dfrac{-1^5}{2^5} = -\dfrac{1}{32}\\\\ \left(\dfrac{1}{2}\right)^6 = \dfrac{1^6}{2^6} = \dfrac{1}{64}$

Bons estudos!
