यदि \(\alpha=\sqrt{3}+1\) और \(\beta=\sqrt{3}-1\), तो \(\alpha\beta\) क्या है?
If \(\alpha=\sqrt{3}+1\) and \(\beta=\sqrt{3}-1\), what is \(\alpha\beta\)?
Explanation opens after your attempt
A. (2)
Concept
(\alpha\beta=\(\sqrt{3}+1\)\(\sqrt{3}-1\)=3-1=2). The irrational part cancels in conjugate multiplication.
Why this answer is correct
The correct answer is A. (2). (\alpha\beta=\(\sqrt{3}+1\)\(\sqrt{3}-1\)=3-1=2). The irrational part cancels in conjugate multiplication.
Exam Tip
(\alpha\beta=\(\sqrt{3}+1\)\(\sqrt{3}-1\)=3-1=2) है। संयुग्मी गुणनफल से अपरिमेय भाग कट जाता है।
