Question

a expa expeçao 5√64-√18/√50-√324

Answer 1

$5 \sqrt{64} - \frac{ \sqrt{18} }{ \sqrt{50} } - \sqrt{324} = \\ \\= 5 \sqrt{2^6} - \frac{ \sqrt{2.3^2} }{ \sqrt{2.5^2} } - \sqrt{2^2.3^4} = \\ \\ = 5 .2^3 - \frac{ 3\sqrt{2} }{ 5\sqrt{2}} - 2.3^2 = \\ \\= 5.8- \frac{3}{5} -2.9= \\ \\ =40- \frac{3}{5} -18= \\ \\ = \frac{5.40-3-5.18}{5} = \\ \\ =\frac{200-3-90}{5} = \frac{200-93}{5} = \frac{107}{5}$
