The answer would be C. Because you would have to have the number of glue sticks on the same side of the fractions otherwise you won't get the right answer.
You can use the order of operations! So we start with 99^3/9. That is 99^2*11. So now let’s do 99/99, it’s 1. So 99^2*11 is 107811, so the answer is 107810.
