कौन-सा विकल्प दो अलग-अलग अपरिमेय संख्याओं का उदाहरण है जिनका भागफल परिमेय है?
Which option is an example of two different irrational numbers whose quotient is rational?
Explanation opens after your attempt
C. \(\frac{\sqrt{5}}{\sqrt{20}}\)
Concept
\(\sqrt{5}\) और \(\sqrt{20}=2\sqrt{5}\) दोनों अपरिमेय हैं और अलग-अलग हैं। / \(\sqrt{5}\) and \(\sqrt{20}=2\sqrt{5}\) are both irrational and different.
Why this answer is correct
\(\frac{\sqrt{5}}{\sqrt{20}}=\frac{\sqrt{5}}{2\sqrt{5}}=\frac{1}{2}\), जो परिमेय है। / \(\frac{\sqrt{5}}{\sqrt{20}}=\frac{\sqrt{5}}{2\sqrt{5}}=\frac{1}{2}\), which is rational.
Exam Tip
भागफल में समान अपरिमेय गुणनखंड कट सकता है। / A common irrational factor can cancel in a quotient.
