If \(a=\sqrt{2}\) and \(b=\sqrt{8}\) then what is (a+b)?
Explanation opens after your attempt
Correct Answer
B. \(3\sqrt{2}\)
Concept
\(\sqrt{8}=2\sqrt{2}\) so the sum is \(3\sqrt{2}\). Simplify before adding.
Why this answer is correct
The correct answer is B. \(3\sqrt{2}\). \(\sqrt{8}=2\sqrt{2}\) so the sum is \(3\sqrt{2}\). Simplify before adding.
Exam Tip
\(\sqrt{8}=2\sqrt{2}\) इसलिए योग \(3\sqrt{2}\) है। पहले सरल रूप निकालें।
