I suppose you mean
Differentiate one term at a time.
Rewrite the first term as
Then the product rule says
Then with the power and chain rules,
Simplify this a bit by factoring out :
For the second term, recall that
Then by the chain rule,
So we have
and we can simplify this by factoring out to end up with
The expression in company B represents that is is in arithmetic progression where first term is 42000 and common difference is 1800 . So we have to use the formula of sum of n terms which is
Where a is the first term, n is the nth term, d is the common difference
On substituting there values,we will get
= 15(84000+52200) = 15*136200 =2043000
And for company A, it is
Difference between them =2043000-2002500= 40500
So the correct option is the second option .
