Powers of 10 "Powers of 10" is a very useful way of writing down large or small numbers. Instead of having lots of zeros, we show how many powers of 10 make that many zeros. Example: 5,000 = 5 × 1,000 = 5 × 10 3. 5 thousand is 5 times a thousand. And a thousand is 10 3. Calculator Use. This is an online calculator for exponents.

Exponentiation is a mathematical operation, written as bⁿ, involving two numbers, the base b and the exponent (or index or power) n.When n is a positive integer, exponentiation corresponds to repeated multiplication; in other words, is product of a number b multiplied by itself n times.. The exponent is usually shown as a superscript to the right of the base.
