2. 25 and 36
3. 6 and 7
4. 7 and 8
5. 8 and 9
6. 9 and 10
7. 18 and 57
8. 9 and 10
9. 12 and 13
10. 3 and 4
Step-by-step explanation:
1. Square roots of non-perfect squares
The number 40 lies between 36 and 49 hence √40 lies between 6 and 7.
2. The number 28 is lies between 25 and 36, therefore 28 is not a perfect square of an integer.
3. between 6 and 7 since 6 is 36 and 7 is 49
4.
5. 8 squared is 64 and 9 squared is 91
6. The square root of 90 lies between 9 and 10.
7.
8. The value of the square root of 85 lies between the whole numbers 9 and 10.
9. So the square root of 150 is going to be between 12 and 13 except for I have to also deal with the negative because I want the negative square root of 150.
10. Similarly, 12 lies between 9 and 16 so √12 lies between 3 and 4.
