Adding negative exponents is done by calculating each exponent first and then adding. X x x 3 x.

X m x n x m n.

How to subtract variables with exponents. They need to be alike to be added or subtracted and the exponents need to match. 4 2 2 5 4 4 2 2 2 2 2 16 32 48. A n b m.

Adding variables with exponents. When an exponent is raised to a power multiply the exponents together. When the exponent is 0 we are not multiplying by anything and the answer is just 1 example y 0 1 multiplying variables with exponents.

Because the variables are the same x and the powers are the same there are no exponents so the exponents must be 1 you. Exponents of 1 and 0 exponent of 1. Adding exponents is done by calculating each exponent first and then adding.

In this case subtract from. Divide two numbers with exponents by subtracting one exponent from the other. Adding same bases b and exponents n.

X 0 1. How to add and subtract with powers. Exponents resources videos links and interactive lessons.

B n b n 2b n. Subtract exponents of like bases. In order to add or subtract variables with exponents you need to have like bases and like exponents which means that the bases and exponents are the same.

Any number raised to the power of zero is equal to one. X y z x y z. Multiply two numbers with exponents by adding the exponents together.

X m x n x m n. The numerical coefficients of these terms may vary and these are the elements that undergo the addition or subtraction process. Attach that exponent to the base and that is your answer.

Like terms consist of the same variable or set of variables raised to the same power. The basic rule in adding and subtracting variables with exponents is they must be like terms. Because the variables are the same x and the powers are the same 2 you can perform the required.

When the exponent is 1 we just have the variable itself example x 1 x we usually don t write the 1 but it sometimes helps to remember that x is also x 1. It does not matter if the bases are letters or even symbols. When two exponents with the same base are being divided subtract the exponent of the denominator from the exponent of the numerator to yield a new exponent.

A n b m 1 a n 1 b m. That yields as the new exponent and as the answer.
