Question

Factorizar punto 3 ;) y 4

Answer 1

Respuesta:

(3) B) 1.

(2) D) 15.

Explicación paso a paso:

$\frac{ {2}^{ - 1} - {3}^{ - 1} }{ {2}^{ - 1} \times {3}^{ - 1} } = \frac{ \frac{1}{2} - \frac{1}{3} }{ \frac{1}{2} \times \frac{1}{3} } \\ \\ = \frac{ \frac{3 - 2}{6} }{ \frac{1 \times 1}{2 \times 3} } = \frac{ \frac{1}{6} }{ \frac{1}{6} } = \frac{6}{6} = 1 \\ \\ \\ log_{15}(x) = {10}^{0} \\ log_{15}(x) = 1 \\ {15}^{1} = x \\ 15 = x$
