$$4\sqrt{6}+4$$

anonymous · Answer

last one, read your book ;-)

anonymous · Answer

I don't have a book.. lol. And are you sure that's it?

anonymous · Answer

That is as far as it simplified as it can get I believe.  With all of these you want to find a way to split the numbers under the radical so that one can actually square.  I'll show you all the steps to this one, so maybe the others will be easier... and here we go

Alright.

Oh, hey! I gotta go. I'm really sorry. When I get back on here though, I'll see what you wrote. Thank you for all your help btw(:

anonymous · Answer

$$\sqrt{2}(\sqrt{8}+4\sqrt{3})$$  you distribute the sqrt of 2, remembering when you multiply two radicals its the same as if you multiplied just the numbers, except under the radical.  so...$$\sqrt{16}+4*\sqrt{6}$$
Now if you look a little you can find 2 numbers that multiply to 16, one of which is a perfect square, those are 3 and 4.  so...
$$\sqrt{3}\sqrt{4}+\sqrt{6}$$

finally just change the sqrt of 4 to a 2 and your done :) and no problem.

whoops, forgot to put the 4 in front of the sqrt of 6 put you'll get it, good luck!
