Explicação passo a passo:

$\mathsf{d)\:\left(\dfrac{3}{4}\right)^4 = \dfrac{3^4}{4^4} = \dfrac{81}{256}}$

$\mathsf{e)\:32^\frac{1}{5} = \sqrt[\mathsf{5}]{\mathsf{32}} = \sqrt[\mathsf{5}]{\mathsf{2^5}} = 2}$

$\mathsf{i)\:a^{12}\:.\:a^5 = a^{12 + 5} = a^{17}}$

$\mathsf{j)\:5^{-4} = \left(\dfrac{1}{5}\right)^4 = \dfrac{1^4}{5^4} = \dfrac{1}{625}}$
