I had to do an accuplacer recently and a few questions stood out that I didn't understand. This was one of them. 64 $\displaystyle \frac{2}{3}$ and the options were 2,4, 8, 16, 32. What math is this? It's not a standard fraction. Last edited by skipjack; May 3rd, 2017 at 02:25 PM.

If you read that as $64^{\frac{2}{3}}$ the answer is $16$.

Why? And yes that is the equation. $64^{\frac{2}{3}}$

Actually, I got it. The 3 is the index, like finding the square root, but with a 3. Then the two squares that number. Thank you.
