# Math Help - checking my anwer

1. ## checking my anwer

simplify by factoring. Assume that all expressions under radicals represent nonegative numbers.

sqrt50a^2b
=sqrt25*2*a^28*b
=sqrt25*sqrt2*sqrta^2*sqrtb
=5a^2bsqrt2
have I got get?

It would be easier to help you if you could put this into LaTex markup.

For example, to get a square root:
$\sqrt{50}$
$$\sqrt{50} [tex] I really don't know if the a^2b is under the square root sign or not. By the way, you should write $a^{2b}$ as [tex]a^{2b}$$

$\sqrt{50a^2b}=\sqrt{25*2*a^2*b}=\sqrt{25}*\sqrt{2} *\sqrt{a^2}*\sqrt{b}=5a\sqrt{2b}$

..

Almost. You had some digits out of place there. I think I've cleaned it up for you now.
