Question

The square root of -8 times the square root of 24

Answer 1

$\sqrt{ -8\sqrt{24} } = \sqrt{-8*2 \sqrt{6} } = \sqrt{-16 \sqrt{6} } = 4i \sqrt{ \sqrt{6} }$

If you studied about complex number, then $4i \sqrt{ \sqrt{6} }$ is your answer. However, if you did not, then the answer should be no solution.
