How to Dealing With Exponents on Negative Bases ?
Exponents work just the same way on negative bases as they do on positive ones:(-2)0 = 1 Any number (except 0) raised to the 0 power is 1.(-2)1 = -2 Any number raised to the first power is that number.(-2)2 = (-2)(-2) = 4 (-2)3 = (-2)(-2)(-2) = -8 (-2)4 = (-2)(-2)(-2)(-2) = 16
Do you notice any pattern here? All the even powers of -2 end up being positive. All the odd powers end up negative. That's a useful trick to know!
