Explanation opens after your attempt

Correct Answer

A. (0)

Step 1

(\(\sqrt{2}\)³=2\sqrt{2}), so \(2\sqrt{2}-2\sqrt{2}=0\). Remember (\(\sqrt{a}\)³=a\sqrt{a}).

Step 2

The correct answer is A. (0). (\(\sqrt{2}\)³=2\sqrt{2}), so \(2\sqrt{2}-2\sqrt{2}=0\). Remember (\(\sqrt{a}\)³=a\sqrt{a}).

Step 3

(\(\sqrt{2}\)³=2\sqrt{2}), इसलिए \(2\sqrt{2}-2\sqrt{2}=0\) है। परीक्षा में (\(\sqrt{a}\)³=a\sqrt{a}) याद रखें।
