To find the best representation of \( \sqrt{13} \) on a number line, we first need to estimate its approximate value.

Calculating \( \sqrt{13} \):

  • We know that \( 3^2 = 9 \) and \( 4^2 = 16 \), so \( \sqrt{13} \) is between 3 and 4.
  • To get a more precise estimate, we can try squaring numbers between 3 and 4.

Calculating:

  • \( 3.5^2 = 12.25 \) (too low)
  • \( 3.6^2 = 12.96 \) (still too low)
  • \( 3.7^2 = 13.69 \) (a bit too high)

This suggests that \( \sqrt{13} \) is approximately 3.6 or 3.7.

Thus, on a number line, \( \sqrt{13} \) would be represented as a point near 3.6, which is between 3 and 4.

You should check the options (A, B, C, D) to see which one is closest to 3.6.
