Answer 2

Answer:

The answer is 0

Step-by-step explanation:

$8\sqrt{45} - 8\sqrt{20} + \sqrt{245} - 3\sqrt{125}\\= 8\sqrt{3^{2}*5} - 8\sqrt{2^{2}*5} + \sqrt{5*7^{2}} - 3\sqrt{5^{2}*5} \\= 8*3*\sqrt{5} - 8*2*\sqrt{5} + 7*\sqrt{5} - 3*5*\sqrt{5} \\= 24\sqrt{5} - 16\sqrt{5} + 7\sqrt{5} - 15\sqrt{5} \\= (24-16+7-15)\sqrt{5} \\= 0*\sqrt{5}\\= 0$

"*" stands for "×"
