Select the correct description for each number set.(4 points)
a) (25−−√, 9, −−−√64−−√
)
b) ( -2.4, 0, 3.1, 81−−√
)
c) (−23, 79, π2
)
d) (12−−√, 11−−√, π
)
a) This number set contains the square root of 25, which is 5, the number 9, and the square root of 64, which is 8. Therefore, the correct description would be: "The number set contains the numbers 5, 9, and 8."
b) This number set contains the numbers -2.4, 0, 3.1, and square root of 81, which is 9. Therefore, the correct description would be: "The number set contains the numbers -2.4, 0, 3.1, and 9."
c) This number set contains the numbers -23, 79, and π/2. Therefore, the correct description would be: "The number set contains the numbers -23, 79, and π/2."
d) This number set contains the square root of 12, which is approximately 3.46, the square root of 11, which is approximately 3.32, and π. Therefore, the correct description would be: "The number set contains the numbers approximately 3.46, approximately 3.32, and π."
