all the others are approximations where you could carry any number of decimal places after the decimal point. Try them with your calculator.
Which equation shows an exact computation?
A. 12/7 = 1.714
B. 2π = 44/7
C. 22/7x14 = 44
D. 2√2 = 2.818
And if possible, could you explain what exact computation is? Thank you.
