QuestionSimplify the expression: $(2 a^{-4})^{3}(a^{5})^{-3}$, ensuring no negative exponents remain.

Studdy Solution
Perform the addition in the exponent.
$$8 \cdot a^{-12+15} =8 \cdot a^{3}$$The expression is now simplified and no negative exponents appear in the final result. The solution is $8 \cdot a^{3}$.
