using a number line what is the approximate value of the square root of 19

Answer 1

Using a number line, we can estimate the approximate value of the square root of 19 as follows:

First, we know that the square root of 16 is 4 and the square root of 25 is 5.

Next, we locate the number 19 on the number line between 16 and 25. Since 19 is closer to 16 than it is to 25, we can estimate that the square root of 19 is slightly greater than 4 but slightly less than 5.

Therefore, the approximate value of the square root of 19 is somewhere between 4 and 5.
