$\frac{(5 \sqrt{3}+ \sqrt{50} )(5- \sqrt{24}) }{ \sqrt{75} -5 \sqrt{2} }=\frac{5\sqrt{3} -5 \sqrt{2} }{5\sqrt{3} -5 \sqrt{2} } =1$

$\\ \\ (5 \sqrt{3} + \sqrt{50} )(5- \sqrt{24} )= \\ =25 \sqrt{3} -5 \sqrt{72} +5 \sqrt{50} - \sqrt{1200} = \\ =25 \sqrt{3} -5 \sqrt{36*2} +5 \sqrt{25*5} - \\ - \sqrt{400*3} =25 \sqrt{3} -5*6 \sqrt{2} + \\ +5*5 \sqrt{2} -20 \sqrt{3} =25 \sqrt{3} -30 \sqrt{2} + \\ +25 \sqrt{2} -20 \sqrt{3} =25 \sqrt{3} -20 \sqrt{3} + \\ +25 \sqrt{2} -30 \sqrt{2} =5 \sqrt{3} -5 \sqrt{2} \\ \\ \sqrt{75} -5 \sqrt{2} = \sqrt{25*3} -5 \sqrt{2} = \\ =5 \sqrt{3} -5 \sqrt{2} \\ \\$
