Find the integers from 1 to 144 which are perfect squares and write the square root of each one.

I'll start you out:

4(2), 9(3), 16(4)….

Take the numbers from 1-12, then square each one.

To find the integers from 1 to 144 that are perfect squares, we need to calculate the square root of each one. Let's start with the first integer, 1.

1 = 1^2, so the square root of 1 is 1.

Next, we move to the next integer, 2. Since 2 is not a perfect square, we skip it.

Next, we move to the next integer, 3. Again, 3 is not a perfect square, so we skip it.

We continue this process until we reach 144.

4 = 2^2, so the square root of 4 is 2.
9 = 3^2, so the square root of 9 is 3.
16 = 4^2, so the square root of 16 is 4.
25 = 5^2, so the square root of 25 is 5.
36 = 6^2, so the square root of 36 is 6.
49 = 7^2, so the square root of 49 is 7.
64 = 8^2, so the square root of 64 is 8.
81 = 9^2, so the square root of 81 is 9.
100 = 10^2, so the square root of 100 is 10.
121 = 11^2, so the square root of 121 is 11.
144 = 12^2, so the square root of 144 is 12.

Therefore, the integers from 1 to 144 that are perfect squares and their square roots are:
1 -> 1
4 -> 2
9 -> 3
16 -> 4
25 -> 5
36 -> 6
49 -> 7
64 -> 8
81 -> 9
100 -> 10
121 -> 11
144 -> 12
