Ok in Pre-Calc we're reviewing Algebra 2 and on my homework I have this problem.

√54xy⁴ And this is how I've worked it out so far.

√54xy⁴

√3²(6)xy⁴

3y² √6x

Did I do that right? I just keep thinking I havent reduced it fully but I cant think of what to do next.

EDIT: Also need some help on this one:

√32a⁴/b²

√2⁵a⁴/b²

4a²/b √2

That is what I have so far.

That's about as far as I got in high school. That was 3 years ago. I'd be interested in knowing the answer too as I'm retaking my assessment for math. Sorry since this is no help to you.

I took Calculus last year and have no clue what you're talking about. :tongue:
