Correct Answer

B. (-10)

Step 1

Concept

\(\sqrt{40}=2\sqrt{10}\), so the bracket is \(-\sqrt{10}\) and the product is (-10). Simplify the bracket first.

Step 2

Why this answer is correct

The correct answer is B. (-10). \(\sqrt{40}=2\sqrt{10}\), so the bracket is \(-\sqrt{10}\) and the product is (-10). Simplify the bracket first.

Step 3

Exam Tip

\(\sqrt{40}=2\sqrt{10}\), इसलिए कोष्ठक \(-\sqrt{10}\) और गुणनफल (-10) है। पहले कोष्ठक को सरल करें।
