Exponents

Exponents are very fun to solve in math problems. I don't know if they ever show them anywhere else. My teacher said to try to find them around. But I can't. Where can you find exponents at. The only place I know where there is exponents is inside my math book which I don't think that is very smart place to find the exponents. Who knows where exponents could be seen around. do you guys know any place where there is any exponents at?
