Question

Preciso de ajuda com a seguinte equação
[(abc) / (a^-2 b ^-2 c^-3)]3

Answer 1

algumas regras: 

$\bmatrix a^x * a^y = a^{x+y}\\\\ \frac{a^x}{a^y} = a^{x-y}\\\\ (a^x)^y = a^{x*y}\\\\a^x*b^x = (a*b)^x\end$

temos:

$\left[ \frac{a*b*c}{a^{-2}*b^{-3}*c^{-3} } \right]^3\\\\\\\ = [a^{[1-(-2)]} *b^{[1-(-2)]}*c^{[1-(-3)]} ]^3\\\\\ = [a^3*b^3*c^4]^3\\\\\ = (a^3)^3 *(b^3)^3*(c^4)^3\\\\ = a^9 * b^9 * c^{12}$
