Get students familiar with the basics, like expressing exponents as products, before you move on to multiplying exponents. Adding the exponents together is just a shortcut to the answer. This rule stays the same, no matter how complicated the question gets.
First, multiply the bases together. Then, add the exponent. Instead of adding the two exponents together, keep it the same. This is because of the fourth exponent rule: distribute power to each base when raising several variables by a power. It might seem complicated, but multiplying exponents with negative numbers is exactly the same as multiplying exponents with non-negative numbers. Begin with reviewing the properties of negative numbers. Specifically, review how to add and multiply them.
Your students need to feel comfortable working with negative numbers before they move on to negative exponents. Then, remember the seventh exponent rule: to change a negative exponent to a positive one, flip it into a reciprocal. Building math fluency is an important part of making sure students feel confident in high school- and college-level math courses.

Solution: Here, the fractional bases and the powers are different. So, first, we will solve each term separately and then move further. When a term has a fractional power, it is called a fractional exponent. Let us understand the rules that are applied to multiply fractional exponents with the help of the following table. Solution: Here, the bases are the same. Solution: Here, the bases are different but the fractional powers are the same.
Solution: Here, the bases and the fractional powers are different. According to the rules of multiplying exponents, when the bases are the same, we add the powers. Multiplying exponents means finding the product of two expressions that have exponents.
Since there are different scenarios like different bases or different exponents, there are different exponent rules that are applied to solve them.
There are some basic rules that are used in almost all the cases. For example,. Yes, expressions with different coefficients can be multiplied. The coefficients are multiplied separately as shown in the example. When exponents with the same bases are multiplied, the powers are added. In order to multiply exponents with different bases and the same powers, the bases are multiplied and the power is written outside the brackets.
However, when we multiply exponents with different bases and different powers, each exponent is solved separately and then they are multiplied.
Multiplying exponents with the same base means when the bases are the same while the exponents are different. In this case, the base is kept common and the different powers are added, i. When exponents are multiplied with parenthesis, the power outside the parenthesis is multiplied with every power inside the parenthesis. There are different rules that are used in multiplying exponents. The basic rules for multiplying exponents are given below.
Multiplying exponents with negative powers follow the same set of rules as multiplying exponents positive powers. The only difference here is that we should be careful with the addition and subtraction of integers for it.
You can see why this works if you study the example shown. According to the "zero rule," any nonzero number raised to the power of zero equals 1.
Negative Exponents. The last rule in this lesson tells us that any nonzero number raised to a negative power equals its reciprocal raised to the opposite positive power.
Rules of 1 There are two simple "rules of 1" to remember. Product Rule The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. Power Rule The "power rule" tells us that to raise a power to a power, just multiply the exponents.
Quotient Rule The quotient rule tells us that we can divide two powers with the same base by subtracting the exponents.
