यदि \(x=\sqrt{2}+\sqrt{8}\), तो (x) का सरल रूप क्या है?

If \(x=\sqrt{2}+\sqrt{8}\), what is the simplified form of (x)?

Explanation opens after your attempt
Correct Answer

A. \(3\sqrt{2}\)

Step 1

Concept

\(\sqrt{8}=2\sqrt{2}\).

Step 2

Why this answer is correct

\(x=\sqrt{2}+2\sqrt{2}=3\sqrt{2}\).

Step 3

Exam Tip

Before adding, convert radicals into like form. चरण 1: \(\sqrt{8}=2\sqrt{2}\)। चरण 2: \(x=\sqrt{2}+2\sqrt{2}=3\sqrt{2}\)। चरण 3: जोड़ने से पहले वर्गमूलों को समान रूप में बदलें।
