    When I took algebra many many years ago they called this rationalization of the denominator. For some reason, mathematicians don't seem to like to leave fractions with a sqrt sign in the denominator. This is how you get it out. 
7/(sqrt x) =
multiply by sqrt x/sqrt x to obtain
7*(sqrt x)/(sqrt x)*(sqrt x) =
7*(sqrt x)/x.
