a) √18
B)√54
C) raiz levando ao cubo de 54
D)√288

Answer 1

$a) \sqrt{18} = \sqrt{2 \times {3}^{2} } = 3 \sqrt{2} \\ b) \sqrt{54} = \sqrt{2 \times 3 \times {3}^{2} } = 3 \sqrt{6} \\ c) \sqrt[3]{54} = \sqrt{2 \times {3}^{3} } = 3 \sqrt{2} \\ d) \sqrt{288} = \sqrt{2 \times {2}^{2} \times {2}^{2} \times {3}^{2} } = 12 \sqrt{2}$
