# Rules of Exponents

The rules of exponents are a set of mathematical operations that can be performed on numbers with exponents. Some of the most commonly used exponent's rules are described in this article.

## Step-by-step to find the Rules of Exponents

The following rules are the most commonly used exponent’s rules:

1. Product of powers: When multiplying two numbers with the same base, add the exponents. For example, $$(a^m)(a^n) = a^{(m+n)}$$
2. Quotient of powers: When dividing two numbers with the same base, subtract the exponent of the denominator from the exponent of the numerator. For example, $$(a^m)/(a^n) = a^{(m-n)}$$
3. Power of a power: When raising a number with an exponent to another power, multiply the exponents. For example, $$(a^m)^n = a^{(mn)}$$
4. Power of a product: When raising a product of numbers to a power, raise each factor to that power. For example, $$(ab)^n = a^n * b^n$$
5. Power of a quotient: When raising a quotient of numbers to a power, raise the numerator and denominator to that power. For example,$$(\frac{a}{b})^n$$ $$=\frac{a^n}{b^n}$$
6. Zero power: any nonzero number raised to the power of zero is $$1$$, for example, $$a^0 = 1$$
7. Negative exponent: When a number is raised to a negative exponent, it is equivalent to the reciprocal of the number raised to the positive exponent. For example, $$a^{-n} =\frac{1}{a^n}$$
8. Exponent of $$1$$: any nonzero number raised to the power of $$1$$ is the number itself, for example $$a^1 = a$$
