Question

$15-7(\frac{27-5^{2} }{11-4}) +2(\frac{3^{3}-9 }{9-6} )$

Answer 1

Explicación paso a paso:

$15-7(\frac{27-5^{2} }{11-4}) +2(\frac{3^{3}-9 }{9-6} )$

$15 - 7( \frac{27 - 25}{7} ) + 2 ( \frac{27 - 9}{3} ) \\ \\ 15 - 7( \frac{2}{7} ) + 2( \frac{18}{3} ) \: simplificamos \\ \\ 15 - 2 + 12 \\ = 25$
