Using a number line, the approximate value of 19−−√ is 4.38.
To find the approximate value of 19 minus the square root, you will need to determine where the square root falls on a number line.
The square root of 19 is between 4 and 5 since the square root of 16 is 4 and the square root of 25 is 5.
Now, we'll have to estimate the decimal value of the square root.
Since 19 is closer to 16 than 25 on the number line, the square root of 19 will be closer to 4 than to 5.
Therefore, the approximate value of 19 minus the square root is around 4.13.
