Can someone help me simplify this?

3rd root of 108 - 3rd root of 32

3V108-3V32

The V's are the square root symbols and the 3's are actually small subscripts representing the 3rd root.

Please help!

(108)^(1/3) - (32)^(1/3)
(4 x 27)^(1/3) - (4 x 8)^(1/3)
(3) 4^(1/3) - (2)(4^(1/3)
4^(1/3)

108^(1/3) - 32^(1/3)

= (2*2*3*3*3)^(1/3) - (2*2*2*2*2)^(1/3)

= 3 * 4^(1/3) - 2 * 4^(1/3)

= 1 * 4^(1/3)

= 4^(1/3)
