यदि \(t=\sqrt{13}+3\) है तो \(t+\frac{4}{t}\) का मान क्या है?
If \(t=\sqrt{13}+3\), what is the value of \(t+\frac{4}{t}\)?
Explanation opens after your attempt
Correct Answer
A. \(2\sqrt{13}\)
Concept
\(\frac{4}{\sqrt{13}+3}=\sqrt{13}-3\) because the denominator becomes (13-9=4). Therefore the sum is \(2\sqrt{13}\).
Why this answer is correct
The correct answer is A. \(2\sqrt{13}\). \(\frac{4}{\sqrt{13}+3}=\sqrt{13}-3\) because the denominator becomes (13-9=4). Therefore the sum is \(2\sqrt{13}\).
Exam Tip
\(\frac{4}{\sqrt{13}+3}=\sqrt{13}-3\) है क्योंकि हर (13-9=4) बनता है। इसलिए योग \(2\sqrt{13}\) है।
