Isn't it X^3 = C*X? seems pretty simple, just multiply both sides by X.

x2 = C

x = +/- C1/2

x3 = +/- C3/2

C^(3/2)  ? Unless there some trick involved.

That's it!

Plainglazed's answer appears to have come in slightly ahead of bonanova's, but both of them are right.

X^2 =C (10^2 = 100)

X^3 = M (10^3 = 1000)

Was a quickie, wasn't it?
