$hi.....$
$3 \sqrt{45} - \sqrt{125} + \sqrt{200} - \sqrt{50}$

$= 3 \sqrt{9 \times 5} - \sqrt{25 \times 5} \\ + \sqrt{100 \times 2 } - \sqrt{25 \times 2}$

$= 3 \times 3 \sqrt{5} - 5 \sqrt{5} + 1 0\sqrt{2} \\ \: \: \: \: - 5 \sqrt{2}$

$= 9 \sqrt{5} - 5 \sqrt{5} + 10 \sqrt{2} - 5 \sqrt{2}$

$= 4\sqrt{5} + 5 \sqrt{2}$

$hence \: simplified.....$
$hope \: \: this \: \: helps.$
