How do i fin the answer to this problem
n5 • k5 • n-5 • k?

To solve this question, remember to apply the exponential law, of multiplying powers with the same base, one must add the exponents.

n^5 • n^-5 • k^5 • k^1
n 5 + -5 • k^5 + 1
n ^0 • k ^6
1 • k^6
k^6.

A) for the n row: 22+(n-1)×6therefore,b) 100-22=78that means (n-1)×6=7878÷6=1313+1=1414th row has 100 seats
