Question 200828: Please walk me through each step in solving this problem:
Simplify by collecting like radical terms, if possible:
3times the cube root of y^5 + 4 times cube root of y^2 + cube root of 8y^6.
They say the answer is (3y+4)times cube root of y^2 + 2y^2.
Sorry I cannor provide the symbol for square root.

Start with the given expression.
Rewrite 8 as
Rewrite as
Rewrite as
Break up the roots using the identity
Evaluate the cube root of to get 2
Evaluate the cube root of to get "y"
Multiply
Factor out the from the first two terms. note: this step isn't necessary, but your book does it.
