Explain Bot To estimate the square root of a number, you can use two known square roots that are close to the number you are estimating. One common technique is to use the square roots of the perfect squares that are closest to the number you want to estimate the square root of.
In this case, you want to estimate the square root of 5. Let's find the closest perfect squares to 5:
- The perfect square less than 5 is 4 (2^2 = 4).
- The perfect square greater than 5 is 9 (3^2 = 9).
So, we can use the square roots of 4 and 9 to estimate the square root of 5.
The square root of 4 is 2, and the square root of 9 is 3. Thus, we can estimate the square root of 5 as being between 2 and 3.
