Simplify (please show work if possible) HELP!!

Answer 1

there is google!

Explanation:

Answer 2

See below.

Explanation:

So we have the expression:

`√(125a^2b^2)`

This is the same as:

`=√((5ab)^2\cdot5)`

Expand:

`=√((5ab)^2)\cdot\sqrt5`

The left term cancels:

`=5|ab|\sqrt5`

Note that we need the absolute value bars because if a and/or b was negative in the original equation, they will turn positive. Thus, to keep things consistent, we must use the absolute value to make sure that a and b stays negative :)
