$|-\sqrt{2}|+\sqrt{9} \times\left(\frac{1}{2}\right)^{-1}-(\pi-\sqrt{2})^0$
$\sqrt{8}+\sqrt{50}-4 \sqrt{\frac{1}{2}} $
$\left(\sqrt{\frac{5}{3}}-\sqrt{\frac{3}{5}}\right) \times \sqrt{20}$
$(\sqrt{2}+\sqrt{3})(\sqrt{2}-\sqrt{3})+(\sqrt{6}+1)^2$
$\frac{\sqrt{27}+2 \sqrt{12}}{\sqrt{3}}$
$(2 \sqrt{3}+3 \sqrt{2})(2 \sqrt{3}-3 \sqrt{2})+2$
$\sqrt{3}(1-\sqrt{3})+\sqrt{12}+\left(\frac{1}{3}\right)^{-1}$
$(\pi-1)^0+\left(-\frac{1}{2}\right)^{-1}+|5-\sqrt{27}|-2 \sqrt{3}$
