    Cubed Root

    10√4m^4 - 3m√32m

    What I've come up with is:

    10√4 x (√m^2)^2 - 6m√4m

    I'm kind of lost and probably off track. Not sure where to go. Please assist. Thanks

    Please use brackets to make it clear what is under each or the roots

    Also try to reframe this as a question, what is it you are required to do with the given expressiosn?

    10√4m^4 - 3m√32m

    The above problem can be written as

    10*(4*m^4)^1/3 - 3m(32m)^1/3

    10m(4m)^1/3 - 6m(4m)^1/3

    Now simplify.
