Remember, to add or subtract numbers that have exponents you must first make sure that the base and exponent of the two terms you are trying to add or subtract are the same. If they are the same, then all you have to do is add together their coefficients and keep the base and exponent the same.
How do u add exponents?
To add exponents, both the exponents and variables should be alike. You add the coefficients of the variables leaving the exponents unchanged. Only terms that have same variables and powers are added. This rule agrees with the multiplication and division of exponents as well.
Do you add exponents when adding like terms?
Like terms have the same variable (letter) and same exponent
We combine them by adding or subtracting the coefficients (the number in front of the letter). The exponents will stay the same after adding or subtracting like terms.
