When dividing two exponential expressions with the same base the quotient has the same base with an exponent that is the difference between the exponents of the dividend and divisor. In Session 41 we will extend this property to values with m n Examples. 6 3 2 3 62 3 3 3 333 27.
Bm bn b m n Examples. The first step to understanding how to deal with fractional exponents is getting a rundown of what exactly they are and then you can look at the ways you can combine exponents when theyre multiplied or divided and they have the same base. 2 6 2 3 2 6-3 2 3 222 8.
We must suppose here that b ne 0 b 0 and both. Step 1 Write down the problem. 1023 1019 102319 104.
X3 x2 x3 2 x5. To multiply two exponential terms with the same base add their exponents. When multiplying two exponential expressions with the same base the product has the same base with an exponent that is the sum of the exponents of the factors.
Or with a number in place of x. Did you notice a relationship between all of the exponents in the example above. When you divided by a larger exponential with the same base the exponent is negative.
When you divide numbers that have the same base subtract the exponents. Bm bn bm nor where m nand b 0. When you have two exponential expressions that have the same base you can easily divide one from another.
Dividing Exponents Rule Example Variable Base Dividing Exponents Rule Example Numerical Base. Multiplying Exponents Rule. Whenever you divide two exponents with the same base you can simplify by subtracting the value of the exponent in the denominator by the value of the exponent in the numerator.

All you have to do in this instance is subtract the exponent of the denominator the. When the bases are different and the exponents of a and b are the same we can divide a and b first. 23 22 25 32.
When you divide two exponential numbers or variables with the same base you subtract the exponents. Dividing exponentshas a very similar rule except you subtract the exponent on the number youre dividing by from the other exponent as described by the formula. This relationship applies to multiply exponents with the same base whether the base is a number or a variable.
Notice that 32 multiplied by 33 equals 35Also notice that 2 3 5. When dividing terms that also contain coefficients divide the coefficients and then divide variable powers with the same base by subtracting the exponents. When dividing exponential expressions with the same base where the base is a nonzero real number copy the common base then subtract the top exponent by the bottom exponent.
For example 34 x 32 34 2 36. Dividing exponents with different bases. Try these on your own Answers will vary 76 8 6 5 83 3 888888 888 83 2 Here is the formal rule when multiplying exponential expressions with the same base.
