The Exponent Laws
By : Fernando Rodriguez
In order to add exponents the equation would have to be multiplication. If the exponent is a fraction you must make sure they have the same denominator in order to add them. If they don't have the same denominator you need to find the LCD (least common denominator) so then you can add the numerator and keep the common denominator.
When Do We Multiply Or Divide The Exponents ?
This might seem be a little confusing but in reality its quite simple. When you have a negative exponents such as x^ -3 you make a fraction and make the exponent positive and then put it at the denominator along with the base. So in that example it would look like 1/x^3. and that is your final answer.
