Limits involving square roots

Hello. I've never been great at math (or spent much time studying), but, since my new major requires quite a few math classes, I have decided to put in as much time as I can to develop my skills. I need help finding a limit for a problem involving square roots. The problem is probably very simple, but I am not sure exactly how to work with the square roots/squares in the problem. I have tried as many approaches as I can think of, and I still feel like I'm getting nowhere.

Could anyone walk me through the steps in solving this? That would be EXTREMELY helpful. The problem:

lim t->2

sqrt( (t+4)(t-2)^4 )

-------------------------

(3t - 6)^2

Sorry, I have no idea how to format that properly. Thanks for any help in advance!

No walk through is available here. We don't do that.

But so

Re: Limits involving square roots

If this is what you mean:

You can start by pulling the (t-2)^4 term out of the square root, then simplify:
