यदि \(OP_a=\sqrt{a}\) और \(OP_b=\sqrt{b}\), जहाँ (b=a+5), तो \(OP_b^2-OP_a^2\) कितना होगा?
If \(OP_a=\sqrt{a}\) and \(OP_b=\sqrt{b}\), where (b=a+5), what is \(OP_b^2-OP_a^2\)?
Explanation opens after your attempt
Correct Answer
C. (5)
Concept
\(OP_b^2=b\) and \(OP_a^2=a\), so the difference is (b-a=5). Square the lengths to remove square roots.
Why this answer is correct
The correct answer is C. (5). \(OP_b^2=b\) and \(OP_a^2=a\), so the difference is (b-a=5). Square the lengths to remove square roots.
Exam Tip
\(OP_b^2=b\) और \(OP_a^2=a\), इसलिए अंतर (b-a=5) है। वर्गमूल हटाने के लिए वर्ग लें।
