-$\sqrt [ 8 ] { x ^ { 6 } }$
A) $\sqrt [ 4 ] { \mathrm { x } ^ { 3 } }$
B) $\sqrt [ 4 ] { x }$
C) $\sqrt { x ^ { 3 } }$
D) $\sqrt { x }$

Question

Quizplus · Accepted Answer

The expression $\sqrt [ 8 ] { x ^ { 6 } }$ can be written with a rational exponent as $x^{6/8}$, which simplifies to $x^{3/4}$. This is equivalent to $\sqrt [ 4 ] { \mathrm { x } ^ { 3 } }$.
