Please, Karla, explain what "C" and "n" represent. Are you talking about combinations (for example, n+2 objects taken n at a time? Or is C some kind of function? I don't quite see the relationship of this problem to 'data management.'
I can’t find the answer. Are you sure this is the whole question?
The third one
U solve from left to right and when two negatives are next to each other it turns to a plus.
C. 9^4
when dividing with exponents, i usually just look at the exponents and subract them so i did 12-8 for this problem
