-exp(-sqrt(x))/(two *sqrt(x)*sqrt(x)) - exp(-sqrt(x))/(two *x^(three / two)) = zero
minus exponent of ( minus square root of (x)) divide by (2 multiply by square root of (x) multiply by square root of (x)) minus exponent of ( minus square root of (x)) divide by (2 multiply by x to the power of (3 divide by 2)) equally 0
