me ajudem por favor é urgente!!!! ​

Answer 1

$2 \sqrt{27} - 5 \sqrt{12} + 10 \sqrt{3} + \sqrt{48} \\ 2 \times 3 \sqrt{3} - 5 \sqrt{12} + 10 \sqrt{3} + \sqrt{48} = 17.32... \\ 6 \sqrt{3} - 5 \sqrt{12} + 10 \sqrt{3} + \sqrt{48} = 17.32... \\ 6 \sqrt{3} - 5 \times 2 \sqrt{3} + 10 \sqrt{3} + \sqrt{48 } = 17.32... \\ 6 \sqrt{3} - 10 \sqrt{3 } + \sqrt{48} = 17.32.. \\ - 4 \sqrt{3} + 10 \sqrt{3} + \sqrt{48} = 17.32... \\ 6 \sqrt{3} + \sqrt{48} = 17.32... \\ 6 \sqrt{3} + 4 \sqrt{3} = 17.32... \\ 10 \sqrt{3} = 17.320508076$
