## anonymous 5 years ago is this correct? sqrt20a^2b=2asqrt5b

1. anonymous

yes

2. anonymous

thank you. just wanted to make sure!

3. anonymous

you are welcome.

If the problem expression is the following: $\sqrt{20a^{2b}}=2a\sqrt{5b}$ then the lhs is not equal to the rhs because $2 \sqrt{5} a^b \neq 2 \sqrt{5} a \sqrt{b}$

5. anonymous

thats not the expression

6. anonymous

What is you understanding regarding the form of the original?

7. anonymous

it is $\sqrt{20a ^{2}b}$
