(2sqrtx)(5sqrtx^3)

Question

Here is what I got:10sqrtx^4
*Is this correct.?

This one is close but still needs to be simplified further.

10√x^4 -->you can take the square root of x^4.

Can you take it from here to finish?

so it will be:10sqrtx^2

No, remember you are taking the square root of x^4, which is x^2, and that comes out from under the square root sign.

You are left with 10x^2 as the simplified form.
