Zero Power
Let me begin by saying that I am doing a self-study of college algebra. I love mathematics. I regret not majoring in math back in my student days. With that said, I hope this forum will allow me to post questions that I get stuck with in my review of college algebra.
Let a = any integer.
Why does a^(0) = 1?
One simple way to see it:
a^3 = (a^4)/a
a^2 = (a^3)/a
a^1 = (a^2)/a = a
a^0 = (a^1)/a = a/a = 1
Does that make sense?
