Answer:
D. √(169/4)
Explanation:
P = √(64/100) = 0.8
Q = √(841/25) = 5.8
Any number between P and Q must have a value between 0.8 and 5.8.
A. √(324/81) = 2
B. √(256/9) = 5.333...
C. √(225/64) = 1.875
D. √(169/4) = 6.5
In the choices, the only expression that does not equal a number between 0.8 and 5.8 is √(169/4).
Answer: D. √(169/4)
