Gerry:

For powers of 2 or 3, just multiply x by itself once or twice.

For larger exponents, something like the following should work:

    Raise X to the Nth power:

        Step 1. Y = 1

        Step 2. N = INT (N/2)
                If N was even, goto Step 5

        Step 3. Y = Y * X

        Step 4. If N = 0, END

        Step 5. X = X * X
                GOTO Step 2
