What two square roots are used to estimate 5

You can use the square roots of 4 and 6 to estimate the square root or 5.

sq. root of 4 and sq. root of 9.

To estimate square roots, we can find the two perfect square numbers on either side of the given number. In this case, we are trying to estimate the square root of 5.

The perfect squares closest to 5 are 4 and 9. The square root of 4 is 2, and the square root of 9 is 3. So, we can estimate that the square root of 5 is between 2 and 3.

However, since 5 is closer to 4, we can conclude that the square root of 5 is slightly more than 2. Therefore, our estimate can be around 2.2 or 2.3.
