Answer 2

$4 \sqrt{2\frac{7}{9} } - 2 = 4 \sqrt{ \frac{25}{9} } - 2 = 4 \times \frac{5}{3} - 2 = \frac{20}{3} - 2 = 6 \frac{2}{3} - 2 = 4 \frac{2}{3}$

$\sqrt{7.5} \times \sqrt{0.3} = \sqrt{7.5 \times 0.3} = \sqrt{2.25} = 1.5$

$\frac{ \sqrt{250} }{ \sqrt{10} } = \sqrt{ \frac{250}{10} } = \sqrt{25} = 5$

$\sqrt{5 {}^{4} \times 2 {}^{4} } = 5 {}^{2} \times 2 {}^{2} = 25 \times 4 = 100$
