यदि \(a=\sqrt{3}+2\) और \(b=\sqrt{3}-2\) हैं तो (ab) क्या है?
If \(a=\sqrt{3}+2\) and \(b=\sqrt{3}-2\), what is (ab)?
Explanation opens after your attempt
A. (-1)
Concept
(ab=\(\sqrt{3}\)2-22=3-4=-1). A conjugate product can be rational.
Why this answer is correct
The correct answer is A. (-1). (ab=\(\sqrt{3}\)2-22=3-4=-1). A conjugate product can be rational.
Exam Tip
(ab=\(\sqrt{3}\)2-22=3-4=-1) है। संयुग्मी गुणनफल परिमेय हो सकता है।
