Question

Please simplify. I will mark as the brainliest.​

Answer 1

Answer:

$= \sqrt{2 + \sqrt{ - 2 + 2 \sqrt{5} } } - \sqrt{2 - \sqrt{ - 2 + 2 \sqrt{5} } } \\ = \sqrt{2 + \sqrt{0 \times \sqrt{5} } } - \sqrt{ 2 - \sqrt{ 0 \times \sqrt{5} } } \\ = \sqrt{2 + 0} - \sqrt{2 - 0} \\ = \sqrt{2} - \sqrt{2} \\ = 0$

therefore the answer is 0
