# Powers of monomials

Here we explain how to find the power of a monomial. Also, you will see several examples of powers of monomials and exercises with solutions to practice.

## How to calculate the power of a monomial

To calculate the power of a monomial, raise each element of the monomial to the exponent of the power. That is, the power of a monomial consists of raising the coefficient and the variable of the monomial to the exponent of the power.

Remember from the properties of powers that when we raise a term that is already raised, the two exponents multiply each other. That is why in the powers of monomials the exponent of each variable (letter) is always multiplied by the exponent that indicates the power.

Note that the result of the power of a monomial depends on the sign of the monomial:

• The power of a positive monomial always results in another positive monomial, regardless of the parity of the exponent:

• A negative monomial raised to an even power equals to a positive monomial:

• A negative monomial raised to an odd power is always equal to another negative monomial:
