Question

Preciso de ajuda !!!!

Answer 1

R: c / d / b / a

$\sqrt{12} + \sqrt{243} \\ 2 \sqrt{3} + \sqrt{81 \times 3} \\ 2 \sqrt{3} + 9 \sqrt{3} \\ 11 \sqrt{3}$

$\sqrt{8} + \sqrt{8} = 2 \sqrt{2} + 2\sqrt{2} = 4 \sqrt{2} = \sqrt{2 \times {4}^{2} } = \sqrt{32}$

$\frac{6}{ \sqrt{6} } \times \frac{ \sqrt{6} }{ \sqrt{6} } = \frac{6 \sqrt{6} }{6} = \sqrt{6}$

$\sqrt{6} \times \sqrt{10} = \sqrt{60} = 2 \sqrt{15}$
