Answer:
C(n, 2)a^(n-2)b^2
Step-by-step explanation:
Generally, the expansion is written in decreasing powers of "a", so the first few terms would have variable constellations that look like ...
a^n, a^(n-1)b, a^(n-2)b^2, ...
The coefficients would be (in order), C(n, k) for k increasing from 0, so the coefficient of the 3rd term would be C(n, 2).
Answer:
5,114.6

<h3>What is a percentage?</h3>
A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given, the population in 2020 is 49992.
40 percentage of population
= 40 % of 49992
= 40 x 49992/100
= 19996.8
Now the population in 1982
= population in 2020 - 40% of population in 1982
= 49992 - 19996.8
= 29995.2
Therefore the population in 1982 is 29995.2.
