Extraer factores. AYUDAA PORFAVOR!!

Answer 1

Respuesta:

$\sqrt{5} - 2 \sqrt{2}$

$2 \sqrt{3}$

$6 \sqrt{2} - 3 \sqrt{5}$

$- \frac {5\sqrt{3}} {27}$

Explicación paso a paso:

a)

$\sqrt{5} + \sqrt{8} - \sqrt{32} \\ = \sqrt{5} + 2 \sqrt{2} - 4 \sqrt{2} \\ = \sqrt{5} - 2 \sqrt{2}$

b)

$\sqrt{54} + \sqrt{12} - 3 \sqrt{6} \\ = 3\sqrt{6} + 2 \sqrt{3} - 3 \sqrt{6} \\ = 2 \sqrt{3}$

d)

$\sqrt{20} + 3 \sqrt{8} - 5 \sqrt{5} \\ = 2\sqrt{5} + 6\sqrt{2} - 5 \sqrt{5} \\ = 6 \sqrt{2} - 3 \sqrt{5}$

e)

$- 4 \sqrt{\frac {1}{27}} + \sqrt{\frac {1}{3}} - 2 \sqrt{\frac {1}{243}} \\ = - \frac {4\sqrt{3}} {9} + \frac {\sqrt{3}} {3} - \frac {2\sqrt{3}} {27} \\ = - \frac {12\sqrt{3}} {27} + \frac {9\sqrt{3}} {27} - \frac {2\sqrt{3}} {27} \\ = - \frac {5\sqrt{3}} {27}$
