Typically, if you do a calculation
with a calculator, unless it's a whole number or terminating
decimal, you will get a sequence of about 9 or 10 digits on screen.
This is an approximation; the actual number has infinitely many
digits.
Exact form tells you that the answer is not supposed to be
approximated. You can't just plug everything into the calculator,
and write out all 9 or 10 digits; you actually have to do some
algebra.
Example: The exact form is 3/2, not 1.5, or sqrt(3), not 1.7, etc. If you are asked for an answer in the exact form, leave it as 3/2 or 1/2.
So in your case,
41)
Midpoint = (3, -4)

Keep these answers as it is to get exact form of answers.
