Explanation opens after your attempt
A. \(14\sqrt{2}\)
Concept
\(\sqrt{8}=2\sqrt{2}\), \(\sqrt{32}=4\sqrt{2}\), and \(\sqrt{128}=8\sqrt{2}\).
Why this answer is correct
The sum is \(2\sqrt{2}+4\sqrt{2}+8\sqrt{2}=14\sqrt{2}\).
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।
