How many electrons can an orbital hold? I know the answer is 2, but how do you get there? And how do you figure out how many 2p orbitals there are in an atom?

math
simplify. x^3/5x^2x^1/2 would i first flip x^1/2 to x^2, therefore x^2 and x^2 would cancel out, so the answer would just be x^3/5? or do i continue to change the exponent into 5 square root of x^3? am i doing this right?
