Which of the following is the square root of 3?

The square root of 3 is approximately 1.732. When evaluating the choices given, the option that is closest to this value is 1.73. This is based on the mathematical fact that the square root of a number is a value that, when multiplied by itself, gives the original number. In this case, since 1.73 multiplied by itself yields a value very close to 3, it is considered the correct answer.

The other options do not accurately reflect the square root of 3. Choosing the closest approximation, 1.73 provides a reliable estimate for practical use. Understanding that square roots can often yield irrational numbers is important, as precise values may extend beyond two decimal places. In this case, it’s beneficial to round to an appropriate number of significant figures while retaining accuracy.
