Can you add two negative exponents?
If the bases are the same, add the exponents. Remember to keep in mind the rules for adding and subtracting negative numbers. If the bases are different but the exponents are the same, multiply the bases and leave the exponents the way they are.
How do you add two numbers with exponents?
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.
Does a negative exponent make the answer negative?
Negative numbers give a negative result when their exponent is odd and they give a positive result when the exponent is even. For example, (-5)3 = -125, (-5)4 = 625. A positive number with a negative exponent will always give a positive number. For example, 2-3 = 1/8, which is a positive number.

How to get rid of negative exponents?
Unless the actual value of x is known, this problem cannot be simplified to a number like in our previous lesson. But this problem can be simplified by getting rid of the negative exponent by following the same steps we did in the previous lesson . First, write the number 1 then divide it by the problem but change the negative exponent to its opposite (The -4 becomes 4).
