Write a method called average that takes two integers as parameters and

returns the average of the two integers.

Modify your pow method from Exercise 5 to make a new method called

pow2 that uses the type double for the first parameter and that works

correctly for negative numbers. For example, the call pow2(–4.0, 3)

should return –4.0 * –4.0 * –4.0, or –64.0, and the call pow2(4.0, –

2) should return 1 / 16, or 0.0625.
