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
Correct Answer

A. (2)

Step 1

Concept

(\alpha\beta=\(\sqrt{3}+1\)\(\sqrt{3}-1\)=3-1=2). The irrational part cancels in conjugate multiplication.

Step 2

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.

Step 3

Exam Tip

(\alpha\beta=\(\sqrt{3}+1\)\(\sqrt{3}-1\)=3-1=2) है। संयुग्मी गुणनफल से अपरिमेय भाग कट जाता है।
