Answer:
16
Step-by-step explanation:
The value of -64 to the power of 2/3 is the same as squaring 64 and then finding the cube root.
So your first step would be to take -64 and multiply it by -64. This gives you 4096. You then take the cubed root of 4096 which is 16.
A cube root is the number that multiplies by itself three times in order to create a cubic value. So when you take 16*16*16 you get 4096.
