When you multiply 2 terms together , you'll need to multiply the numbers then add the exponents. Combine the terms if you need to. Distribute each of the term for the 1st polynomial to each term according to the 2nd polynomial.
This is a geometric sequence, so use the formula for the sum of a geometric sequence:
Sum = (a(r^n - 1))/(r - 1)
where a is the first term, -5
r is the common ratio, 5
and n is the number of terms
Thus,
Sum = ((-5)(5^6 - 1))/(5-1) = -19530
Answer
N = 32 ÷ (5 - 1)
N = 32 ÷ 4
N =8
