 \sqrt{8} + \sqrt{32} = \sqrt{4.2} + \sqrt{16.2} = 2\sqrt{2} + 4\sqrt{2} =6 \sqrt{2}

\sqrt{27} + \sqrt{3} = \sqrt{9.3} + \sqrt{3} = 3\sqrt{3} + \sqrt{3} =4 \sqrt{3}

3\sqrt{5} + \sqrt{20} = 3\sqrt{5} + \sqrt{4.5} = 3\sqrt{5} + 2\sqrt{5} =5 \sqrt{5}

2\sqrt{2} + \sqrt{18} = 2\sqrt{2} + \sqrt{9.2} = 2\sqrt{2} + 3\sqrt{2} =5 \sqrt{2}
5 4 5
se não for pedir demais poderia resolver essa pra mim
