Answer 1

Answer:

$\: \: \: \: \: \: \\ 39 \sqrt{2} + 3 \sqrt{3}$

Step-by-step explanation:

$2 \sqrt{18} - 3 \sqrt{48} - 3 \sqrt{98} + 5 \sqrt{27} + 9 \sqrt{72} \\ \\ = 2 \sqrt{9 \times 2} - 3\sqrt{16 \times 3} - 3 \sqrt{49 \times 2} + 5 \sqrt{9 \times 3} + 9 \sqrt{36 \times 2} \\ \\ = 2 \sqrt{ {3}^{2} \times 2} - 3\sqrt{ {4}^{2} \times 3} - 3 \sqrt{ {7}^{2} \times 2} + 5 \sqrt{ {3}^{2} \times 3} + 9 \sqrt{ {6}^{2} \times 2} \\ \\ = 6 \sqrt{2 } - 12 \sqrt{3} - 21 \sqrt{2} + 15 \sqrt{3} + 54 \sqrt{2} \\ \\ = 39 \sqrt{2} + 3 \sqrt{3}$
