Using a number line, what is the approximate value of 19−−√ ?(1 point) Responses 4.25 4.25 4.13 4.13 4.5 4.5 4.38
To approximate the value of √19 using a number line, we can look for two perfect square numbers that 19 is between.
The perfect square numbers that are closest to 19 are 16 (4^2) and 25 (5^2).
Since 19 is closer to 16 than it is to 25, we can say that √19 is closer to √16, which is 4.
Therefore, the approximate value of √19 is 4.
So the answer is 4.
