Question

PLEASE HELP
What is the following sum?

Answer 1

In order to add radical terms, you need the same index and the radicand.

The terms we are adding up meet both of those criteria. So, we can add them up.


`4( \sqrt[5]{x^2y} ) + 3( \sqrt[5]{x^2y} ) = 7(\sqrt[5]{x^2y})`

So,
`7(\sqrt[5]{x^2y})` is the answer.
