For example if your problem is m to the 4th power divided by m to the 2nd power then you would subtract 2 from 4 in order to get 2. Division is the opposite of multiplication so it makes sense that because you add exponents when multiplying numbers with the same base you subtract the exponents when dividing numbers with the same base.
To divide exponents or powers with the same base subtract the exponents.
How to divide with exponents. To divide exponents with the same base start by subtracting the second exponent from the first. For example if your problem is m to the 4th power divided by m to the 2nd power then you would subtract 2 from 4 in order to get 2. That means your final answer is m to the 2nd power.
Dividing exponents with different bases. When the bases are different and the exponents of a and b are the same we can divide a and b first. A n b n a b n.
6 3 2 3 62 3 3 3 333 27. When the bases and the exponents are different we have to calculate each exponent and then divide. A n b m.
6 2 3 3 36 27 1333. For exponents with the same base we can subtract the exponents. A-n a-m a-n–m a m-n.
You can divide exponential expressions leaving the answers as exponential expressions as long as the bases are the same. To divide exponents or powers with the same base subtract the exponents. Division is the opposite of multiplication so it makes sense that because you add exponents when multiplying numbers with the same base you subtract the exponents when dividing numbers with the same base.
When the bases and the exponents are different we have to calculate each exponent and then divide. A-n b-m b m a n. 2-3 5-2 5 2 2 3 25 8 3125.
Dividing fractions with exponents. Dividing fractions with exponents with same fraction base. A b n a b m a b n-m.
62 4 62 3 62 4-3 62 1 3. Or equivalently of subtracting 1 from the exponent in the numerator. Just as we did last week with the product rule we can write a rule to summarize how division with exponents works.
This rule called the quotient rule for exponents says that. 2m 2n 2m-n. The letters m and n here are placeholders that can represent any number.
In one of our earlier problems m was 3 n was 1 and the division problem 23 21 was equal to 23-1 22. Learn how to divide exponents by using the division property of exponents in a few simple steps. Step by step guide to divide exponents.

Y 2 y 3 yy yyy. This final video revises multiplying exponents and then later on gets into dividing exponents. It also shows the fast track rules of adding Exponents for Multiplying Problems and Subtracting Exponents for Dividing Problems.
Y 2 y 3 yy yyy. Just subtract the exponents of the variables we are dividing by. Here is a bigger demonstration involving several variables.
The zs got completely cancelled out. Which makes sense because z 2 z 2 1 To see what is going on write down all the multiplies then cross out the variables that are both top and bottom. X3 y z2 x y2 z2 xxx y zz x yy zz x xx y zz x y y zz xx y x2 y.
Both polynomials should have the higher order terms first those with the largest exponents like the 2 in x 2. Divide the first term of the numerator by the first term of the denominator and put that in the answer. Dividing Fractional Exponents With the Same Base.
Tackle divisions of two numbers with fractional exponents by subtracting the exponent youre dividing the divisor by the one youre dividing the dividend. X 1 2 x 1 2 x 1 2 1 2 x 0 1. To divide exponents or powers with the same base subtract the exponents.
