Question

Determine between which two whole numbers lies square root of 20​

Answer 1

The square root of 20 is approximately between 4 and 5.

To find this, you can estimate the square root of 20 by finding the square root of the closest perfect squares, which are 16 (4^2) and 25 (5^2):

√16 = 4

√25 = 5

Since 20 is closer to 25 than 16, we know that the square root of 20 must be closer to 5 than to 4. Therefore, the square root of 20 lies between 4 and 5.
