Answer 2

Hey friend, ☺️ here is your answer ____________________________

$3 \sqrt{45} - \sqrt{125} + \sqrt{200} - \sqrt{50} \\ = 3 \sqrt{3 \times 3 \times 5} - \sqrt{5 \times 5 \times 5} + \sqrt{2 \times 2 \times 5 \times 2 \times 5} - \sqrt{5 \times 2 \times 5} \\ = 3 \times 3 \sqrt{5} - 5 \sqrt{5} + 2 \times 5 \sqrt{2} - 5 \sqrt{2} \\ = 9 \sqrt{5} - 5 \sqrt{5} + 10 \sqrt{2} - 5 \sqrt{2} \\ = 4 \sqrt{5} + 5 \sqrt{2}$
Hope this helps you..
