Math Problem Statement

Which point best approximates √3?

Solution

The question is asking which point on the number line best approximates 3\sqrt{3}.

We know that 31.732\sqrt{3} \approx 1.732.

Looking at the number line:

  • Point A is at 0.
  • Point B is at 1.
  • Point C is at 2.
  • Point D is at 3.

Since 3\sqrt{3} is approximately 1.732, it lies between points B (1) and C (2). Therefore, the best approximation for 3\sqrt{3} is closest to C.

  1. How is the square root of a number approximated on a number line?
  2. Can square roots of non-perfect squares be represented as exact fractions?
  3. What is the decimal approximation of 2\sqrt{2} and where would it fall on this number line?
  4. How do irrational numbers like 3\sqrt{3} differ from rational numbers?
  5. Why do we use approximations for square roots of non-perfect squares?

Tip: To get better at estimating square roots, remember that n\sqrt{n} for non-perfect squares lies between two whole numbers.
