Answer:
[tex]64^\frac{1}{12}[/tex]
Step-by-step explanation:
[tex]\sqrt[4]{64}[/tex]
has the meaning of [tex]64^\frac{1}{4}[/tex]
That means that what you have is
[tex]64^\frac{1}{4}*^\frac{1}{3}[/tex]
which means that your final answer is
[tex]64^\frac{1}{12}[/tex]
That would be the answer that I try first. In fact the question is set up in such a way that I would ignore the fact that 64^(1/3) = 4
