power [%PREMIUM_LINK%] (pou'ər) Pronunciation Key |
In mathematics, a power is a number multiplied by itself the number of times signified by an exponent placed to the right and above it. Thus, 32, which means 3 × 3, is a power — the second power of three, or three squared, or nine. The expression 106, or ten to the sixth power, means 10 × 10 × 10 × 10 × 10 × 10, or one million.
