 Question 4485: The question I have is this. C = W^2L^3 ------- 24T^2 I am trying to solve for "W". The solution the book gives is W= "the square root of both the numerator and denominator" (CL^3) ------- (24T^2) I understand that to just get "W" from W^2 you have to take the square root of it and what you do to one side you must do to the other, but how does "C" and "W" both stay in the numerator on both sides if you must use the reciprocol to move them on the different sides of the equasion?
