Correct Answer

A. \(2\sqrt{220}\)

Step 1

Concept

\(x^2=22+10+2\sqrt{220}=32+2\sqrt{220}\). So \(x^2-32=2\sqrt{220}\).

Step 2

Why this answer is correct

The correct answer is A. \(2\sqrt{220}\). \(x^2=22+10+2\sqrt{220}=32+2\sqrt{220}\). So \(x^2-32=2\sqrt{220}\).

Step 3

Exam Tip

\(x^2=22+10+2\sqrt{220}=32+2\sqrt{220}\) है। इसलिए \(x^2-32=2\sqrt{220}\) है।
