### Some questions on the GED math test will involve exponents and powers, so it is important the you understand the basics and how to solve them.

Exponents and powers are a way to show repeated multiplication. For example, 2^4 means the base of 2 is multiplied 4 times. In other words, 2^4 = 2 x 2 x 2 x 2 = 16.

Any number raised to the zero power is one. For example, 10^0 = 1 or 56^0 also equals one. An exception is zero raised to the zero power which is undefined.

Any number raised to the one power is itself. For example, 12^1 = 12.
