take each terms and sqaure root it

square root of 45 = 9
square root of a^3 = a * squareroot of a
square root of b^ 8 = b ^ 4

put them together

9ab^4 square root of a

Ok how would I go about doing this one?

Exactly the same way as all the other ones.

(45)^1/2 a^3/2 b^4

All the problems you are posting are identical in concept, just with different values.

Going to rewrite this next problem right off as ( a^12 b^4)^1/4

nothing its called a 4th root

Does my answer look right. I'm pretty sure it is.

No, I gave you the answer already:

45^1/2 a^3/2 b^4

Edit: Typo.

I think mine is right too though. I wonder if they form the same equation?
