Question

Raiz3/(raiz8-10)(raiz2+5)-18

Answer 1

$\frac{ \sqrt{3}}{( \sqrt{8}-10).( \sqrt{2} +5) } -18 = ? \\ \\ \frac{ \sqrt{3} }{ \sqrt{8} . \sqrt{2} +5 \sqrt{8}-10 \sqrt{2}-50 } -18 = \frac{ \sqrt{3} }{ \sqrt{16} +5 \sqrt{8}-10 \sqrt{2}-50 }-18 \\ \\ \frac{ \sqrt{3} }{4 + 5 \sqrt{ 2^{2}.2 } - 10 \sqrt{2}-50 } -18= \frac{ \sqrt{3} }{4 + 10 \sqrt{2} - 10 \sqrt{2}-50 }-18 = \frac{ \sqrt{3}}{-46} -18 = \frac{ -\sqrt{3}-828}{46}$
