Hi,

I can't solve this radical equation, can someone help?

8³√x+3 =11

Incase someone has a hard time reading that, because I know, sometimes I do, it says eight, cube root, x+3=11. The x+3 is inside the cube root, but the 11 is not.

x=4, but I don't know how the person who told me got it.

Thanks-

Isabel
