how do you do √50x√18?
~~~~~~~~~~~~~~~~~~~~~~ 

I treat the square roots as having positive values and 'x' as the multiplication sign.


It is what should be told in the problem's description, but since it is omitted,
I insert it to make your request sensible.


Then  sqrt%2850%29 * sqrt%2818%29 = sqrt%2850%2A18%29 = sqrt%28900%29 = 30.    ANSWER

Solved.
