Hi, I'm have a little difficulty solving out this problem. I would really appreciate it if someone were able to help me out. Thank you in advance.
as you see from my working, all i did was simplify $\displaystyle \sqrt[5]{972}$, i left it to you to add this to $\displaystyle 3 \sqrt[5]{4}$.
just treat $\displaystyle \sqrt[5]{4}$ as $\displaystyle x$.
so if you had $\displaystyle 3x + 3x$, what would the answer be?
