Work Step by Step

You have ($\frac{a^4a}{a^2}$$)^{-3}$.Simplify the expression: $a^{4+1-2}$ -simplify the expression insides the parentheses by adding the exponents on the numerator and then subtracting 2 because you are dividing- (a$^3$)$^-$$^3$ apply exponent rule $x^{-y}$=$\frac{1}{x^y}$- $\frac{1}{(a^3)^3}$ -simplify the exponents- The simplified expression is $\frac{1}{a^9}.$
