The answer is A because square root of 81 is 9 and 90.—— is the square root of 9.5. Therefore square root 86 is between 9 and 9.5

I am certain that A is the answer and heres why:

[tex] \sqrt{81} =9 [/tex]

[tex] \sqrt{90} = 9.86 [/tex]

90.25 is the highest number you can have for "A" to be true and 86 is the lowest. Given that 86 is in between both of these numbers we can only assume that answer "A" would work the best
