Answer:
6
Step-by-step explanation:
The square root of 36 is 6 and the square root of 49 is 7.
Since 39 falls in between 36 and 49, you know that the square root of 39 is going to be somewhere between 6 and 7.
Because 39 is significantly closer to 36 than it is 49, the approximation of the square root of 39 to the nearest whole number would be 6.
