(-5)²-3²+(2/3)°
_____________ =
-²
3 + 1/5+1/2

Answer 1

$\frac{(-5)^2-3^2+ (\frac{2}{3})^0 }{ 3^{-2} + \frac{1}{5}+ \frac{1}{2} } = \\ \\ = \frac{25-9+ 1}{ \frac{1}{3^2} + \frac{1}{5}+ \frac{1}{2} }= \\ \\ = \frac{25-8}{ \frac{1}{9} + \frac{1}{5}+ \frac{1}{2} }= \\ \\ = \frac{17}{ \frac{10.1+18.1+45.1}{90} }= \\ \\ = \frac{17}{ \frac{73}{90} } =17. \frac{90}{73} = \frac{1530}{73}$
