Substitute each of the capital letters in bold by a different digit from 0 to 9 to satisfy this alphametic equation. Neither A nor C is zero and S ≥ 2.

C
∫ x^-S dx = .COLORS
A

Yes, I agree with your result Charlie.

I guess s>=2 is to steer us away from s=1 and consequent logarithms.

- but I'm still puzzled.. Did you assume s=5 when you did the integral?
