Which point on the number line is represented by \( -\sqrt{0.36} \)?

Answer and explanation

Correct answer: \(-0.6\)

\(\sqrt{0.36}=0.6\) because \(0.6^2=0.36\). The negative sign outside the radical makes the entire value negative, so \(-\sqrt{0.36}=-0.6\). Option B ignores the outside negative sign, while C and D have incorrect decimal values. Exam tip: first evaluate the principal square root, then apply any sign outside the radical.
