If you're using doubles throughout, then you'll

want to use Math.Pow( x, tothepower );

If you're using integers throughout, you might

want to consider multiple multiplies.

However, this is probably not going to be an

'inefficient' part of your program, so using Pow()

will most likely suffice. My guess is that VB uses

Pow() under the covers anyway.
