Question

How many integers are between square root of 7 and 220​

Answer 1

Explanation:

sqrt(7) is larger than 2 (2² = 4) but smaller than 3 (as 3² is 9).

sqrt(220) is larger than 14 (14² = 196) but smaller than 15 (15² = 225).

so, the integers between them are

3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14

these are 12 integer values.
