Answer 2

Answer:

$- 54 \sqrt{3} + 24 \sqrt{3}$

Step-by-step explanation:

$\sqrt{867} + \sqrt{147} - 3 \sqrt{648} \\ = \sqrt{17 \times 17 \times 3} + \sqrt{7 \times 7 \times 3} - 3 \times \sqrt{9 \times 9 \times 4 \times 2} \\ = 17 \sqrt{3} + 7 \sqrt{3} - 54 \sqrt{2} \\ = 24 \sqrt{3} - 54 \sqrt{2}$
