If m and n are positive integers, each of the following could be equivalent to,
$$\sqrt{800mn}\ Except.$$
$$A.\ \ 80\sqrt{m}$$
$$B.\ \ 40\sqrt{10m}$$
$$C.\ \ 40m\sqrt{5}$$
$$D.\ \ 20\sqrt{5m}$$
$$E.\ \ 20\sqrt{2m}$$
The OA is D.
I'm really confused with this PS question. Please, can any expert assist me with it? Thanks in advanced.
