Explanation opens after your attempt
Correct Answer
B. \(10\sqrt{7}\)
Concept
\(\sqrt{28}=2\sqrt{7}\), \(\sqrt{63}=3\sqrt{7}\), and \(\sqrt{175}=5\sqrt{7}\).
Why this answer is correct
The sum is \(2\sqrt{7}+3\sqrt{7}+5\sqrt{7}=10\sqrt{7}\).
Exam Tip
Once radicals become like terms, add only the coefficients. चरण 1: \(\sqrt{28}=2\sqrt{7}\), \(\sqrt{63}=3\sqrt{7}\), और \(\sqrt{175}=5\sqrt{7}\)। चरण 2: योग \(2\sqrt{7}+3\sqrt{7}+5\sqrt{7}=10\sqrt{7}\) है। चरण 3: समान वर्गमूल बनने पर केवल गुणांक जोड़ें।
