If \(x=\sqrt{5}+\sqrt{5}\) then what is (x)?

C. \(2\sqrt{5}\)
Simple Explanation
यहाँ दोनों पद समान करणी हैं: \(\sqrt{5}\) और \(\sqrt{5}\)। इसलिए उनके गुणांक जोड़े जाते हैं: \(1\sqrt{5}+1\sqrt{5}=2\sqrt{5}\)। अतः सही उत्तर \(2\sqrt{5}\) है। \(\sqrt{10}\) गलत है, क्योंकि \(\sqrt{5}+\sqrt{5}\) को \(\sqrt{5+5}\) नहीं लिखा जा सकता। परीक्षा टिप: केवल समान करणी वाले पदों के गुणांक जोड़े या घटाए जाते हैं। / Both terms are like surds: \(\sqrt{5}\) and \(\sqrt{5}\). Hence, add their coefficients: \(1\sqrt{5}+1\sqrt{5}=2\sqrt{5}\). Therefore, the correct answer is \(2\sqrt{5}\). \(\sqrt{10}\) is incorrect because \(\sqrt{5}+\sqrt{5}\) cannot be written as \(\sqrt{5+5}\). Exam tip: add or subtract only the coefficients of like surds.
