Question

resuelve utilizando la propiedad de la multiplicación de
$\sqrt{72} \times \sqrt{2}$
$\sqrt{5} \times \sqrt{2} \times \sqrt{10}$
$\sqrt{6} \times \sqrt{2} \times \sqrt{3}$
$\sqrt{5} \times \sqrt{3} \times \sqrt{15}$
​

Answer 1

$\sqrt{72} \: x \: \sqrt{2} = \sqrt{9x8} \: x \: \sqrt{2} = \sqrt{ {3}^{2} x {2}^{2}x2 } \: x \: \sqrt{2} = 3x2 \sqrt{2} \: x \: \sqrt{2} = 6 \sqrt{ {2}^{2} } = 6x2 = 12$

$\sqrt{5 } \: x \: \sqrt{3} \: x \: \sqrt{15} \: = \sqrt{5x3} \: x \: \sqrt{15} = \sqrt{ {15}^{2} } \: x \: \sqrt{15} = \sqrt{ {15}^{2} } = 15$
