Using the Quotient of Powers Property
This video lesson will explore the Quotient of Powers Property which states that when dividing two exponents with the same base, you can subtract the exponents and keep the base. This property will always work as long as the base is not...

Dividing Fractions
👉 Learn how to divide fractions. To divide two fractions, we multiply the first fraction by the reciprocal of the second fraction. (The reciprocal of a fraction is swapping the positions of the numerator and the denominator). It is...
