That means 4 times the cubic root of 135.

mathstudent55 · Answer

In order to simplify that, you need to find the factors of 135.

anonymous · Answer

ughhh 1, 3, 5, 9, 15, 27, 45, and 135

anonymous · Answer

they need to add to get 4 right? so 3 and 1?

mathstudent55 · Answer

I mean prime factors, 2, 3, 5, 7, 11, 13, etc.
Start with the smallest prime number and see if 135 is divisible by it. If so divide by it.
Start withh 2. Is 135 divisible by 2? No.
Move on to 3. Is 135 divisible by 3?
