Find two consecutive whole numbers that the square root of 105 lies between

Answer: 10 and 11, also - 11 and - 10

Sqrt 100 is well known to be 10

Sqrt 121 is 11

Step-by-step explanation:

Positive Sqrt is monotone increasing

So Sqrt 105 is between sqrt 100 and sqrt 121

Second answer

Sqrt 100 is less well known to also be - 10

Negative sqrt is monotone decreasing

Sqrt 121 is also - 11

Sqrt 105 is also between - 121 and - 100
