Why does y^0 = 1?

a) Because y^{1} multiplied by y = 1

b) Because y^{-1} multiplied by y = 1

c) Because y^{1} divided by y = 1

d) Because y^{-1 }divided by y = 1

Isn't this an easy problem? Are they allowing me to pick only one answer even though both are correct?

well i think the answer is C bc u normally learn about positive exponents and then u learn about 0 and the negatives. But they should both be true.

Thank you. I've been working on exponents for a long time. I guess I'll just try one and see what happens.
