Correct Answer

B. \(9\sqrt{7}\)

Step 1

Concept

\(\sqrt{847}=11\sqrt{7}\), \(\sqrt{363}=7\sqrt{7}\), and \(\sqrt{147}=3\sqrt{7}\). So the result is \(11\sqrt{7}-7\sqrt{7}+3\sqrt{7}=7\sqrt{7}\).

Step 2

Why this answer is correct

The correct answer is B. \(9\sqrt{7}\). \(\sqrt{847}=11\sqrt{7}\), \(\sqrt{363}=7\sqrt{7}\), and \(\sqrt{147}=3\sqrt{7}\). So the result is \(11\sqrt{7}-7\sqrt{7}+3\sqrt{7}=7\sqrt{7}\).

Step 3

Exam Tip

\(\sqrt{847}=11\sqrt{7}\), \(\sqrt{363}=7\sqrt{7}\) और \(\sqrt{147}=3\sqrt{7}\) है। इसलिए परिणाम \(7\sqrt{7}\) नहीं, \(11\sqrt{7}-7\sqrt{7}+3\sqrt{7}=7\sqrt{7}\) है।
