Question

gente me ajuda please​

Answer 1

Explicação passo-a-passo:

(-1/3)^-2 : (-1/3)^9

As bases são iguais portanto:

(-1/3)^-2-9

(-1/3)^-11

ou seja:

$(-\frac{1}{3})^{-11}$

Answer 2

$\frac{(\frac{-1}{3})^{-2}}{(\frac{-1}{3})^9}\\\\\frac{(\frac{-3}{1})^2}{(\frac{-1}{3})^9}\\\\\frac{\frac{3^2}{1}}{\frac{-1}{3^9}}\\\\\frac{3^2.3^9}{-1}\\\\\frac{3^{11}}{-1}\\\\(\frac{-1}{3})^{-11}$
