Answer 2

a. correct if you are doing boolean functions. if not, you need to do something else

b. if you consecutive sum is n+m and start at 0=m and count up. then n state the same

c. correct but I would write as 3(n^2) is its essay other people can understand clearly

d. m the sum of n mean add n together mth times, and is +

e. cube mean power of __. (hint: it Wright after square).

liner = n^1

non liner= n^n, where n is not = 1

and look at only the highest n power
