Question

0,003/10-2 + radical 500- 50 /radical5

Answer 1

$\frac{\frac{3}{1000}}{8} + \frac{\sqrt{500} -50}{ \sqrt{5} } = \frac{8x3}{1000} + \frac{\sqrt{5} x( \sqrt{500} -50)}{5} =$
$\frac{6}{25} + \frac{1250000-50 \sqrt{5} }{5} = \frac{6}{25} + \frac{50x(25000- \sqrt{5} )}{5}$
$\frac{6}{25} +625000-25 \sqrt{5} =6+15625000-50 \sqrt{5} =15625006-50 \sqrt{5}$
