Question

How do you simplify `5sqrt(2x) * 4sqrt(10x)`?

Answer 1

`40xsqrt5`

Explanation:

Put together like terms - multiply proper numbers, then multiply square roots, and then put them all together.

`4*5=20`
`sqrt(2x)*sqrt(10x)=sqrt(20x^2)=2xsqrt5`

And putting them back together,

`20*2xsqrt5=40xsqrt5`
