Answer 1

Answer:

31.492

Step-by-step explanation:

$48 - 3 \sqrt{72} - \sqrt{27} + 5 \sqrt{18} \\ 48 - 3 \times 6 \sqrt{2} - 3 \sqrt{3} + 5 \times 3 \sqrt{2} \\ 48 - 3 \times 6(1.414) - 3(1.732) + 5 \times 2(1.414) \\ 48 - 18(1.414) - 3(1.732) + 10(1.414) \\ 48 - 25.452 - 5.196 + 14.14 \\ 62.14 - 30.648 \\ 31.492$
