**DrBob222**, Monday, January 14, 2008 at 11:38pmLook at a number such as -2. Raised to an even power (say 2) is -2*-2 = +4.

Or raised to 4 (another even power) is -2*-2*-2*-2 = +16. Both 4 and 16 are positive numbers.

Raise -2 to an odd power (say 3) and we have -2*-2*-2 = -8 (a negative answer).

Or raised to -5 is

-2*-2*-2*-2*-2 = -32 (a negative answer). You should be able to get the connection from these example.
