Which statement gives the correct position of (-\sqrt{4}) on the number line?

Answer and explanation

Correct answer: −2

First, \(\sqrt{4}=2\). The negative sign outside the square root makes the value negative, so \(-\sqrt{4}=-(\sqrt{4})=-2\). Therefore, the point is \(-2\) on the number line. Exam tip: do not confuse \(-\sqrt{4}\) with \(\sqrt{-4}\).
