$\large\tt \color{black}{3\sqrt{50}-8\sqrt{2}}$


$\large\tt \color{black}{=3\sqrt{5\times5\times2}-8\sqrt{2}}$


$\large\tt \color{black}{=3\times5\sqrt{2}-8\sqrt{2}}$


$\large\tt \color{black}{=15\sqrt{2}-8\sqrt{2}}$


$\large\tt \color{black}{=(15-8)\sqrt{2}}$

$\large\tt \color{black}{=(7)\sqrt{2}}$

$\large\tt \color{black}{=(7)(1.41)}$
