Help! Need it for the ALEKS test! My Calc is kinda rusty (2years).
No need for calculus... For starters, remember that the product of square roots is equal to the square root of the product. So $\displaystyle \displaystyle \begin{align*} \sqrt{2x^2v^3}\sqrt{10x^4v^6} = \sqrt{2x^2v^3 \cdot 10x^4v^6} \end{align*}$. Go from here.
Then I think I remember from school we used to factor out the perect squares..? So like sqrt(20*x^4*x^2*y^9)... So lost! Am I on the right track here? I feel like I'm confusing another process with this one.
