I need help with this problem: (sqroot 5)*(sqroot .0025)/(sqroot .0009)

$\displaystyle \frac {\sqrt 5 \sqrt{.0025}}{\sqrt {.0009}}$ $\displaystyle = \sqrt {\frac {5 \times .0025}{.0009}}$ $\displaystyle = \sqrt {\frac {5 \times 25}{9}}$ $\displaystyle = \sqrt 5 {\frac {5}{3}}$ ... I think.

Wouldn't the $\displaystyle \sqrt{5}$ also get multiplied by 100 when you multiply to get rid of the decimal points?
yes
No $\displaystyle \frac {\sqrt 5 \times 0.05}{0.03} = \frac {\sqrt 5 \times 5 \times 0.01}{3 \times 0.01}$ You only got one 0.01 on top and bottom to cancel with each other.
oops thanks for pointing that out
Ohhhh...I get it. Thank you everyone for all your help.
