You can use the exponent operator "^" or you can use the Math.Pow method. The difference is that the exponent operator can only be used with integers while either or both values can be fractional with Math.Pow.
Oops! I'm thinking VB.NET. "^" has a different meaning in C#. I'm sure there must be an exponent operator but I don't know what it is. Anyway, you can definitely use Math.Pow.
Or maybe not. I just checked the C# Reference in the help and there appears to be no exponent operator. Maybe that's why the Math.Pow method exists. Chalk one up for VB.NET.
