Explanation opens after your attempt
Correct Answer
A. \(\sqrt{2}\)
Concept
\(\sqrt{8}=2\sqrt{2}\), so \(\sqrt{8}-\sqrt{2}=\sqrt{2}\). In exams simplify radicals first.
Why this answer is correct
The correct answer is A. \(\sqrt{2}\). \(\sqrt{8}=2\sqrt{2}\), so \(\sqrt{8}-\sqrt{2}=\sqrt{2}\). In exams simplify radicals first.
