Products of Exponents (Product Rule) Worksheets
We explore how to approach multiplying pairs of exponential values that share the same base number. When you come across an example like this: m4 x m2. The product rule of exponents tells us that if we are multiplying exponents with the same base, we simply add the exponents to determine the product. This means that m4 x m2 = m6 (4 + 2). This is a nice rule that is helpful to speed up our calculations especially when condensing expressions and equations. These worksheets and lessons help students learn how to multiply values that have attached exponents.

What is the Product Rule of Exponents?
Thanks to the shorthand rule in mathematics, we don’t have to write long numbers that can literally take up the whole page. Exponents are a shorthand method followed in mathematics to write up repeated multiplication of the same number by itself. The variable or number that is being multiplied is called the base number, and the number of times it’s being multiplied is written as many times as the exponent is. The exponent concept is not new to many of us. However, the product rule of exponents might be something new for many of us. Consider the following example:
The product of x3 . x4 = x . x . x (3 factors) multiplied by x . x . x . x (4 factors).
In the above example, you can find a cube of x and 4 times of x being multiplied. As per the product rule of exponent, when the bases of two exponential numbers are the same, you can add the exponents of the two numbers. Like in this case, you can add the powers/exponents of x which are 3 and 4. Hence, the answer becomes x3 + 7 = x 10. This is the product rule of an exponent.
The product rule can be visualized the formula: ab x ac = ab + c
This holds true not just for individual values, but whole exponential expressions as well.
