Take out 2020^2019

\(\frac{2020^{2019}(2020^2-1)}{2020^{2019}(2020^1-1)}\)

Erase the 2020^2019

\(\frac{2020^2-1}{2020^1-1}\)

Which is 2021

Why, hello there flec :omighty:

all must bow down!!!

to perfect scorer on IMO

Anyways, we can recognize that \(2020^{2020}-2020^{2019}=2020^{2019} \cdot 2020-2020^{2019}=2020^{2019} \cdot 2019\) and then simplify the top similarly. After canceling some terms, we will be left with the answer.

Henlo! And no, don't bow down to me, I did NOT score a perfect on the IMO, I'm not even close to qualifying to IMO!

I wonder who you are

Nice answer, by the way!
