Question

Quizplus · Accepted Answer

When raising a power to a power, you multiply the exponents. Thus, $x^9$ raised to the 3rd power becomes $x^{9*3} = x^{27}$, and $y$ raised to the 3rd power becomes $y^3$, making the correct answer $x^{27}y^3$.

Simplify Write the Answer Using Positive Exponents Only (x9y)3\left( x ^ { 9 } y \right) ^ { 3 }(x9y)3
