when I try to put this into the algebrator, I cannot seem to simplify
How do I dothis?

OK.. so where is this located..I have the algebrator that will only allow me to write the number 2 after my control R- I have been having a terrible time with this..

Sqrt (3w^3 u^4) Sqrt (15w^2u) =
Sqrt {(3w^3 u^4)(15w^2u)} =
Sqrt( 45 x (uw)^5} =
Sqrt{5 x 3^2 x (uw)^4 x uw} =
3 x (uw)^2 x Sqrt(5uw)

The correct answer is 3w^2u^2*sqrt(5wu). Yupchagee multiplied 3 * 15 and got 90, when it should have been 45....

Sqrt (3w^3 u^4) Sqrt (15w^2u)
sqrt(90w^5u^5)
3w^2u^2*sqrt(10wu)

Pull out any squares you can:
wu²√(3w)*w√(30u)
Now combine like terms
w²u²√(90wu)
One more 3 can come out:
3w²u²√(10wu)

First you fix your ability to expand square roots
