Explanation opens after your attempt
Correct Answer
C. (7)
Concept
\(\sqrt{45}=3\sqrt{5}\) and \(\sqrt{80}=4\sqrt{5}\), so the numerator is \(7\sqrt{5}\). Dividing by \(\sqrt{5}\) gives (7).
Why this answer is correct
The correct answer is C. (7). \(\sqrt{45}=3\sqrt{5}\) and \(\sqrt{80}=4\sqrt{5}\), so the numerator is \(7\sqrt{5}\). Dividing by \(\sqrt{5}\) gives (7).
Exam Tip
\(\sqrt{45}=3\sqrt{5}\) और \(\sqrt{80}=4\sqrt{5}\), इसलिए अंश \(7\sqrt{5}\) है। \(\sqrt{5}\) से भाग देने पर (7) मिलता है।
