We divide 40 by 1/2:-
40 / 1/2 = 40 * 2/1 = 80 answer
7 = r^1/2 is the same as saying 7 = square root of r. So, to get rid of the square root sign on the r, you need to square it, and when you do something to one side of the equation, you have to do the same to the other side. So after squaring both sides, you get 49 = r.
