Question

2 raiz de 24 + raiz de 54 - raiz de 150 (tem que fatorar o 24,54 e 150)

Answer 1

$2 \sqrt{24} = 2 \sqrt{4 x 2 x 3} = 2 x 2 \sqrt{2x3} = 4 \sqrt{6}$
-
$\sqrt{54} = \sqrt{3x9x2} = 3 \sqrt{3x2} = 3 \sqrt{6}$
-
$\sqrt{150} = \sqrt{25x6} = 5 \sqrt{6}$
-
$4\sqrt{6} + 3\sqrt{6} - 5 \sqrt{6}$
$2\sqrt{6}$
