Powers and Exponents

Powers and exponents are commonly used in math. When first observing a mathematical problem that involves powers and exponents, the problem might seem very complicated. But, powers and exponents are, in fact, very simple to use once you understand how to use them.

In order for you to discover the powers of a number, you must repeatedly multiply that number by itself. The first power is the number that you are multiplying by itself. The second power is the number that you get when you multiply the first power by itself. In other words, the second power is the product of the first power number. The third power is the first power number multiplied by itself two times. The fourth power is the number multiplied by itself three times. The fifth power is the number multiplied by itself four times, the sixth power is the number multiplied by itself five times, and so on and so forth.

The number two, for example, is the first power of two. Times that by itself and you get four. Four is the second power of two. Eight is the third power of two. Sixteen is the fourth power of two. Thirty-two is the fifth power of two. Sixty-four is the sixth power of two.

One way to write the power of a number is by placing a tiny number above and to the right of the number. Two would be the tiny number if you are indicating the second power of the larger number. This way of writing the power of a number is called an exponent.
