Question

The square root of a number is between 10 and 11. Which of these could be that number?

A. 166


B. 83


C. 105


D. 95

Answer 1

Well we can do this by checking the value of each radical.

A. =
`√(166)` = 12.88 (this is too much)

B. =
`√(83)` = 9.11 (this is too little)

C. =
`√(105)` = 10.24 (this is PERFECT!)

D. =
`√(95)` = 9.74 (this is too much)

The reason why radical 105 is perfect is because it is between 10 and 11 just like the question asks.

SO YOUR ANSWER IS C

Answer 2

the answer is C) 105
