One way is to estimate
1^2=1
2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
the number 61 is between 49 and 64 therefor the square root of 61is between the intigers 7 and 8 or -7 and -8
Question 9 is A, and question 10 is 10^5.
If hugo has 1400 and on the 2 month it is c
{8, 16, 24, 32}int.{16, 32, 48}={16, 32}
