Alguém sabe a resposta?

Answer 1

Vamos resolver. Qualquer dúvida, avise:

$\dfrac{(-5)^23^2+\left(\frac{2}{3}\right)^0}{3^{-2}+\frac{1}{5}+\frac{1}{2}}=\dfrac{25.9+1}{\frac{1}{9}+\frac{1}{5}+\frac{1}{2}}\\ \\ \\ = \dfrac{225+1}{\frac{10}{90}+\frac{18}{90}+\frac{45}{90}}=\dfrac{226}{\frac{73}{90}}\\ \\ \\ =226\cdot\dfrac{90}{73}\boxed{=\dfrac{20340}{73}}$
