When we encounter exercises or expressions with terms that have the same base and between them the sign of division or fraction line, we can subtract the exponents.

We will subtract the exponent in the denominator from the exponent in the numerator.

That is:

"exponent of the denominator - exponent of the numerator" = new exponent

The result obtained from the subtraction is the new exponent and we will apply it to the original base.

**Formula of the property:**

$\frac {a^m}{a^n} =a^{(m-n)}$

This property also concerns algebraic expressions.
