We just have to work with variables as well as numbers. 1) Factor the radicand (the numbers/variables inside the square root). Factor the number into its prime factors and expand the variable (s). 2) Bring any factor listed twice in the radicand to the outside.

WebTo eliminate a cube root, you need a perfect cube inside the radical (something cubed). You are starting with cuberoot (2). The 2 has an exponent of 1. To create a perfect cube, you need to create 2^3 = 8 inside the radical. Thus we multiply: 1/cubert (2) * cubert (2^2)/cubert (2^2) = cubert (2^2)/cubert (2^3) = cubert (4)/2 Hope this helps.
