Post subject:  GRE Algebra 
Please explain how this equation works out: s² / (s²√3 / 4) = 4s² / (s²√3) = 4 / √3 = (4√3) / 3 I am with each step, crossing out the s², and then you have 4 / √3. But how does 4 / √3 turn into 4√3 / 3? Isn't that an extra three? I think what I really need is a lesson in multiplying/dividing by radicals. I always seem to mess them up and the only thing I ever read is telling me to group radicals together and treat regular numbers separately. I do not see anything that goes into depth. Please help!
