Please help, it's urgent!
Aneli [31]

For this case we have to, by defining properties of powers and roots the following is fulfilled:

\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}

We must rewrite the following expression:

\sqrt [3] {8 ^ {\frac {1} {4} x}}

Applying the property listed we have:

\sqrt [3] {8 ^ {\frac {1} {4} x}} = 8 ^ {\frac{\frac {1} {4} x} {3} }= 8 ^ {\frac {1} {4 * 3} x} = 8 ^ {\frac {1} {12} x}

Using the property again we have to:

8 ^ {\frac {1} {12} x} = \sqrt [12] {8 ^ x}

Thus, the correct option is option C

Answer:

Option C
