Are you sure that's right?

2. anonymous

√48a^5b 4√ 3 a^4 ------- = ------- = 2a^4 √12ab 2√3

3. anonymous

Yeah that looks more like it!

4. anonymous

oh - i could have done it easier - because √48 / √12 = √4 = 2

5. anonymous

Could you answer some more for me please?

6. anonymous

$\sqrt{\frac{48 a^5 b}{12a b}}=2 a^2$

7. anonymous

yeah - but please post them separately - if theres a few post them together

8. anonymous

oh rob may be right - does the √ reger to just the number or all of the expression - i assumed it was just the number

@jimmyrep Yes, it's another ambiguous radical symbol. Assumed that it covered the entire expression length.

@jimmyrep I usually don't answer problems like this one where there is a question regarding the presentation.
