कौन सा विकल्प (\(\sqrt{2}+\sqrt{5}+\sqrt{8}\)) का सरल रूप है?
Which option is the simplified form of (\(\sqrt{2}+\sqrt{5}+\sqrt{8}\))?
Explanation opens after your attempt
Correct Answer
A. \(3\sqrt{2}+\sqrt{5}\)
Concept
\(\sqrt{8}=2\sqrt{2}\), so \(\sqrt{2}+\sqrt{8}=3\sqrt{2}\). The unlike root \(\sqrt{5}\) remains separate.
Why this answer is correct
The correct answer is A. \(3\sqrt{2}+\sqrt{5}\). \(\sqrt{8}=2\sqrt{2}\), so \(\sqrt{2}+\sqrt{8}=3\sqrt{2}\). The unlike root \(\sqrt{5}\) remains separate.
Exam Tip
\(\sqrt{8}=2\sqrt{2}\) इसलिए \(\sqrt{2}+\sqrt{8}=3\sqrt{2}\) होता है। असमान जड़ \(\sqrt{5}\) अलग रहती है।
