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.
