As estimate for square root 47 is between _____________
1: 4 and 5
2: 5 and 6
3: 6 and 7
4: 7 and 8
Is the answer 6 and 7?
6 and 7, yes
Correct.
To estimate the square root of a number, it helps to find two perfect squares on either side of the number. The perfect squares that are closest to 47 are 36 (which is 6^2) and 49 (which is 7^2).
Since 47 is between 36 and 49, the estimate for the square root of 47 is between 6 and 7. Therefore, the correct answer is option 3: 6 and 7. Well done!
