For 41 and 42 how to give exact form of answer ?
Find the distance and the midpoint of the pair of given points. Give your answer in exact form 41) (4.-1) and (2,-7) t 36 Find the missing length(s) in the right triangle. Write your answer in exact form? 42) a +o 2 8 43) 10 cm

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.

Midpoint = (3, -4)

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