What is the value of (\(5+\sqrt{3}\)\(5-\sqrt{3}\))?
Explanation opens after your attempt
B. (22)
Concept
This is \(a^2-b^2\), so the value is (25-3=22). Conjugate multiplication removes the radical.
Why this answer is correct
The correct answer is B. (22). This is \(a^2-b^2\), so the value is (25-3=22). Conjugate multiplication removes the radical.
Exam Tip
यह \(a^2-b^2\) है इसलिए मान (25-3=22) है। संयुग्मी गुणन में मूल हट जाता है।
