Quizplus · Accepted Answer

When raising a power to another power, you multiply the exponents. Therefore, $$\left( \frac { x ^ { 7 } } { 3 } \right) ^ { 3 }=\frac{x^{7\cdot 3}}{3^3}=\frac{x^{21}}{27}$$

Simplify - (x73)3\left( \frac { x ^ { 7 } } { 3 } \right) ^ { 3 }(3x7​)3

Simplify
- $\left( \frac { x ^ { 7 } } { 3 } \right) ^ { 3 }$
