To find the approximate value of √19, we will use a number line.
Start by estimating the square root of 16, which is 4 since 4² is equal to 16. Then, move slightly to the right towards 19 on the number line.
Since 19 is closer to 16 than 25 (which is the square of 5), we can estimate that √19 is slightly larger than 4.
Among the given options, the value that is closest to our approximation is 4.38. Therefore, the approximate value of √19 is 4.38.
