Changing the subject of a formula
Find r when V = 4/3?r^3
Next I have multiplied by 3 giving
3V = 4?r^3
Then divide by 4? giving
r^3 = 3V/4?
Here is where I am not sure, do I cube root both sides?
Like r = cube root 3v/4?
Thanks in advance.

Apart from that, all's fine; good stuff!
Show this way: r = [3v / (4?)]^(1/3)
