\(\sqrt{2}+\sqrt{2}\) का सरल रूप किस प्रकार की संख्या है?
The simplified form of \(\sqrt{2}+\sqrt{2}\) is what type of number?
Explanation opens after your attempt
Correct Answer
B. अपरिमेय संख्याIrrational number
Concept
\(\sqrt{2}+\sqrt{2}=2\sqrt{2}\).
Why this answer is correct
\(\sqrt{2}\) is irrational and (2) is non-zero rational, so \(2\sqrt{2}\) is irrational.
Exam Tip
First simplify like radicals, then decide the type. चरण 1: \(\sqrt{2}+\sqrt{2}=2\sqrt{2}\)। चरण 2: \(\sqrt{2}\) अपरिमेय है और (2) अशून्य परिमेय है, इसलिए \(2\sqrt{2}\) अपरिमेय है। चरण 3: समान वर्गमूलों को पहले जोड़कर सरल करें।
