With tables, they would show you growth that happened, but not the same amount of growth after x amount of time because you would be increasing by a factor and not a constant number.
And equations, you would be increasing by a percentage mostly likely.
So remember some exponentional laws
![\frac{x^n}{x^m}=x^{n-m}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%5En%7D%7Bx%5Em%7D%3Dx%5E%7Bn-m%7D%20%20)
and
![x^{-n}= \frac{1}{x^{n}}](https://tex.z-dn.net/?f=%20x%5E%7B-n%7D%3D%20%5Cfrac%7B1%7D%7Bx%5E%7Bn%7D%7D%20%20)
so
4 to the 6th root=4^(1/6)
4 to the 3rd root=4^(1/3)
so
![\frac{4^{1/6}}{4^{1/3}} =4^{(1/6)-(1/3)}=4^{(1/6)-(2/6)}=4^{-1/3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%5E%7B1%2F6%7D%7D%7B4%5E%7B1%2F3%7D%7D%20%3D4%5E%7B%281%2F6%29-%281%2F3%29%7D%3D4%5E%7B%281%2F6%29-%282%2F6%29%7D%3D4%5E%7B-1%2F3%7D)
and
![4^{-1/3}= \frac{1}{4^{1/3}}= \frac{1}{ \sqrt[3]{4} }](https://tex.z-dn.net/?f=%204%5E%7B-1%2F3%7D%3D%20%5Cfrac%7B1%7D%7B4%5E%7B1%2F3%7D%7D%3D%20%5Cfrac%7B1%7D%7B%20%5Csqrt%5B3%5D%7B4%7D%20%7D%20%20%20)
the answer is
10/12, 15/18, 20/24, 25/30, 30/36
4,0
that is the ordered pair of the solution:)
