Using rational approximations, what statement is true?
A. √81 < 9
B. √81 > 9
C. √71 > √61
D. √71 < √61
B. √81 > 9
To determine the truth of each statement using rational approximations, let's calculate the approximate values:
A. √81 ≈ 9 (True)
B. √81 ≈ 9 (True)
C. √71 ≈ 8.44 and √61 ≈ 7.81 (True)
D. √71 ≈ 8.44 and √61 ≈ 7.81 (True)
Based on the rational approximations, the correct statement is:
C. √71 > √61
