Answer 2

$3 \sqrt{125} - 4 \sqrt{45} + \sqrt{500} - \sqrt{180}$

simplify it

$3 \sqrt{25 \times 5} - 4 \sqrt{9 \times 5} + \sqrt{25 \times 2 \times 2 \times 5 } - \sqrt{45 \times 2 \times 2}$

$3 (5)\sqrt{5} - 4(3) \sqrt{5} + 5(2) \sqrt{5 } - \sqrt{9 \times 5 \times 4}$

$15 \sqrt{5} - 12 \sqrt{5} + 10 \sqrt{5} - 3(2) \sqrt{5}$

$25 \sqrt{5} - 12 \sqrt{5} - 6 \sqrt{5}$
