Question

$2 \sqrt{3.5 \sqrt{8 = } }$

Answer 1

$2 \sqrt{3 \times 5 \sqrt{8} } = \\ 2 \sqrt{3 \times 5 \times 2 \sqrt{2 = } } \\ 2 \sqrt{30 \sqrt{2 = } } \\ 2 \sqrt{ \sqrt{30 {}^{2} } } \sqrt{2} = \\ 2 \sqrt{ \sqrt{30 {}^{2} \times 2} } = \\ 2 \sqrt{ \sqrt{2 \times 30 {}^{2} } } = \\ 2 {}^{4} \sqrt{2 \times 30 {}^{2} } = \\ 2 {}^{4} \sqrt{2 \times 900} = \\ 2 {}^{4} \sqrt{1800}$
