\(\sqrt{8}+\sqrt{32}+\sqrt{128}\) का सरल रूप क्या है?

What is the simplified form of \(\sqrt{8}+\sqrt{32}+\sqrt{128}\)?

Explanation opens after your attempt
Correct Answer

A. \(14\sqrt{2}\)

Step 1

Concept

\(\sqrt{8}=2\sqrt{2}\), \(\sqrt{32}=4\sqrt{2}\), and \(\sqrt{128}=8\sqrt{2}\).

Step 2

Why this answer is correct

The sum is \(2\sqrt{2}+4\sqrt{2}+8\sqrt{2}=14\sqrt{2}\).

Step 3

Exam Tip

With many radicals, simplify all of them first. चरण 1: \(\sqrt{8}=2\sqrt{2}\), \(\sqrt{32}=4\sqrt{2}\), और \(\sqrt{128}=8\sqrt{2}\)। चरण 2: योग \(2\sqrt{2}+4\sqrt{2}+8\sqrt{2}=14\sqrt{2}\)। चरण 3: कई वर्गमूल हों तो पहले सबको सरल रूप में लिखें।
