Answer 2

Answer:

15√2 or 35.355 approx.

Step-by-step explanation:

$12 \sqrt{18} - 3 \sqrt{50} + \sqrt{32} \\ = 12 \sqrt{3 \times 3 \times 2} - 3 \sqrt{5 \times 5 \times 2} + \sqrt{2 \times 2 \times 2 \times 2 \times 2} \\ = 12 \sqrt{ {3}^{2} \times 2 } - 3 \sqrt{ {5}^{2} \times 2} + \sqrt{ {4}^{2} \times 2 } \\ = 12 \times 3 \ \sqrt{2} - 3 \times 5 \sqrt{2} + 4 \sqrt{2} \\ = 36 \sqrt{2 } - 15 \sqrt{2} + 4 \sqrt{2} \\ = 15 \sqrt{2}$
