Question

Whats the square root of 39 to the nearest integer

Answer 1

To the nearest integer, the square root of 39 would be 6.

Explanation:

To find the answer, look at the perfect squares on either side of 39. Lower than it would be 36 and the next highest would be 49. Since it is closer to 36, we can estimate that the answer is 6.

Answer 2

6

Explanation:

We can list the squares

1^2=1

2^2 =4

3^2 =9

4^2 = 16

5^2 =25

6^2 =36

7^2=49

39 is closest to 36

sqrt(36) < sqrt(39) < sqrt(49)

6<sqrt(39) <7

39 is closer to 36 than 49 so it is closer to 6 than 7
