Question

Efetue as operações com radicais. pfv alguem me ajuda

Answer 1

$\sqrt{2 {}^{2} } \times 3 + \sqrt{3 {}^{2} } \times 3 {}^{2} \times 3 + 2\sqrt{3 \times 3} = \\ 2 \sqrt{3} + 3 \times 3 \sqrt{3} + 2 \sqrt{3 \times 3} = \\ 2 \sqrt{3} + 6 \sqrt{3} + 2 \sqrt{6} = 8 \sqrt{3} + 2 \sqrt{6}$

$\sqrt{2} + \sqrt{8} + \sqrt{18} = \sqrt{2} + \sqrt{2^{2} } \times 2 + \sqrt{3^{2} } \times 2 = \\ \sqrt{2} + 2 \sqrt{2} + 3 \sqrt{2} = 6 \sqrt{2}$
