The laws of exponents, sometimes known as the rules of exponents, are the rules and properties of exponents you use when simplifying or evaluating expressions containing exponents. The laws of exponents include definitions for what fractional exponents, negative exponents, and even different exponential expressions mean.

Remember, exponents are just a way of simplifying how many times a number is multiplied by itself. A number multiplied by itself *n* times can be denoted with an exponent *n*. This is called raising a number to its *nth* power. For example, 3 x 3 x 3 x 3 x 3 x 3 is the same as 3⁶, or three raised to the sixth power.
