यदि \(a=\sqrt{98}\) और \(b=\sqrt{50}\) तो (a-b) क्या है?
If \(a=\sqrt{98}\) and \(b=\sqrt{50}\), what is (a-b)?
Explanation opens after your attempt
Correct Answer
B. \(2\sqrt{2}\)
Step 1
Concept
\(\sqrt{98}=7\sqrt{2}\) and \(\sqrt{50}=5\sqrt{2}\). Hence the difference is \(2\sqrt{2}\).
Step 2
Why this answer is correct
The correct answer is B. \(2\sqrt{2}\). \(\sqrt{98}=7\sqrt{2}\) and \(\sqrt{50}=5\sqrt{2}\). Hence the difference is \(2\sqrt{2}\).
Step 3
Exam Tip
\(\sqrt{98}=7\sqrt{2}\) और \(\sqrt{50}=5\sqrt{2}\)। इसलिए अंतर \(2\sqrt{2}\) है।
