Answer 1

$\sqrt{0.09 \times 64} = \sqrt{0.3 {}^{2} \times 8 {}^{2} } = 0.3 \times 8 = 2.4$

$\sqrt{ {5}^{2} \times {2}^{6} } = 5 \times \sqrt{( {2}^{3}) {}^{2} } = 5 \times {2}^{3} = 5 \times 8 = 40$

$\sqrt{50} \times \sqrt{2} = \sqrt{100} = \sqrt{ {10}^{2} } = 10$

$\frac{ \sqrt{300} }{ \sqrt{3} } = \sqrt{ \frac{300}{3} } = \sqrt{100} \sqrt{ {10}^{2} } = 10$
