"Integral Exponents"

We cannot simplify expressions that do not have like terms because then there won't be nothing to combine. X^2y and xy^2 are not like terms because even though they have the same variables & exponents they are not written the same way. Xy and xyz cannot be combined because they do not have the same variables. The power of m^7 is 7, and the base is m. A negative base is a number or variable including a negative sign. If the base is x the negative base will be -x. A real life scenario involving exponents will be when you are putting carpet in your room.
