    Thanks for posting in the correct forum :smile:

    Yes, those square-root problems are tricky at first.

    We do need to see an attempt (by you) at solving the problem before we offer help. Your textbook probably has an example worked out, involving a square-root function. Look at that, see what you can come up with, and then post here again.
