This means that there is no number, except 1, that can be divided evenly into both the numerator and the denominator. To reduce a fraction to lowest terms, divide the numerator and denominator by their Greatest Common Factor (GCF). This is also called simplifying the fraction.
Answer:
![-\frac{9}{r^4}](https://tex.z-dn.net/?f=-%5Cfrac%7B9%7D%7Br%5E4%7D)
Step-by-step explanation:

![\frac{d}{dr} (r^n)=nr^{n-1}\\-\frac{9}{r^4}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdr%7D%20%28r%5En%29%3Dnr%5E%7Bn-1%7D%5C%5C-%5Cfrac%7B9%7D%7Br%5E4%7D)
If a=20 then 5a would be 100 because 5*20=100
