किस विकल्प में दो अपरिमेय संख्याओं का गुणनफल परिमेय लेकिन योग अपरिमेय है?
In which option do two irrational numbers have a rational product but an irrational sum?
Explanation opens after your attempt
A. \(\sqrt{12}\) और \(\sqrt{3}\)\(\sqrt{12}\) and \(\sqrt{3}\)
Concept
\(\sqrt{12}=2\sqrt{3}\) and \(\sqrt{3}\) are both irrational.
Why this answer is correct
Their product is \(\sqrt{36}=6\), which is rational, and their sum is \(3\sqrt{3}\), which is irrational.
Exam Tip
Check the nature of the sum and product separately. चरण 1: \(\sqrt{12}=2\sqrt{3}\) और \(\sqrt{3}\) दोनों अपरिमेय हैं। चरण 2: उनका गुणन \(\sqrt{36}=6\) परिमेय है, और योग \(3\sqrt{3}\) अपरिमेय है। चरण 3: योग और गुणन की प्रकृति अलग-अलग जाँचें।
