Question

What is the cube root of 512 m^2n^15

Answer 1

8

Explanation:

It depends what mathematics you know

Perhaps the most basic way would be by approximation. You could start with, say, 5. 5*5*5= 125. Then 5 is to small to be the cube root of 512.

Try 10: 10*10*10=1000: Too bi. But now we know that the number we want is between 5 and 10.

Try 8: 8*8*8=512.
