Answer 1

Hey friend, ☺️ here is your answer _____________________________

$6 \sqrt{45} + 4 \sqrt{50} + \sqrt{405} \\ = 6 \sqrt{3 \times 3 \times 5} + 4 \sqrt{2 \times 5 \times 5} + \sqrt{3 \times 3 \times 3 \times 3 \times 5} \\ = 6 \times 3 \sqrt{5} + 4 \times 5 \sqrt{2} + 3 \times 3 \times \sqrt{5 } \\ = 18 \sqrt{5} + 20 \sqrt{2} + 9 \sqrt{5} \\ = 27 \sqrt{5} + 20 \sqrt{2}$
Hope this helps you..
