Answer 1

$\frac{(-5)^{2}-3^{2}+(\frac{2}{3})^{0} }{3^{-2}+\frac{1}{5}+\frac{1}{2} }=$

$\frac{25-9+1}{\frac{1}{9}+\frac{1}{5}+\frac{1}{2} } =$

$\frac{17}{\frac{10+18+45}{90} }=$

$17.\frac{90}{73} =\frac{1530}{73}$

Resposta final: $\frac{(-5)^{2}-3^{2}+(\frac{2}{3})^{0} }{3^{-2}+\frac{1}{5}+\frac{1}{2} }= \frac{1530}{73}$
