the problem is 500= 1 --- 1 --- X 2 Your presentation of the problem is unclear. Please repost. If you mean "X squared," that is indicated by "X^2." I hope this helps a little. Thanks for asking.

same question, but it didn't come across right. 500 equals 1 over X to the half 500 = 1/(X^1/2) Multiply both sides by X^1/2. 500*X^1/2 = (1*X^1/2)/X^1/2. X^1/2 divides out on the right side leaving 500*X^1/2 = 1. Now square both sides. [500*X^1/2]^2 = 1....
