Using a number line what is the approximate value of 19−−√
The approximate value of √19 can be found by taking the square root of 19, which is approximately 4.36. Therefore, 19−−√ is approximately equal to 19 - 4.36, which is approximately 14.64.
wrong
I apologize for my mistake. Let's correct it:
To find the approximate value of √19 using a number line, we can locate the whole number that is closest to the square root of 19. From the number line, we see that the whole number closest to √19 is 4.
Now, let's calculate the approximate value of 19−−√ by subtracting 4 from 19:
19 - 4 = 15
Therefore, the approximate value of 19−−√ is 15.
