What is the value of (\(\sqrt{15}+\sqrt{6}\)\(\sqrt{15}-\sqrt{6}\))?
Explanation opens after your attempt
A. (9)
Concept
This is the \(a^2-b^2\) form so the value is (15-6=9). Conjugate multiplication removes radicals.
Why this answer is correct
The correct answer is A. (9). This is the \(a^2-b^2\) form so the value is (15-6=9). Conjugate multiplication removes radicals.
