To find the approximate value of √19, we can estimate it on a number line.
Starting at 0 on the number line, we can find the square root of 19 by estimating where it would fall between whole numbers.
The square root of 16 is 4, which is too low. The square root of 25 is 5, which is too high.
So, √19 is approximately between 4 and 5 on the number line.
To estimate more accurately, we can divide the distance between 4 and 5 into smaller intervals.
We can divide it into 10 equal intervals since there are 10 numbers between 4 and 5 on the number line.
Each interval would be 1/10 of the distance between 4 and 5.
If we label the intervals 1, 2, 3, ..., 9, 10, then 0.1 represents the distance between each interval.
By counting the intervals from 4 to the approximate position of √19, we can find the answer.
Counting the intervals, we find that √19 is approximately between 4.1 and 4.2 on the number line.
So, the approximate value of 19−−√ is 4.1 or 4.2.
Among the given options, the closest value is 4.13.
Therefore, the approximate value of 19−−√ is 4.13.
