Question

4×{+2-5+[-1-2+3]3×(+2-1)-4}

Answer 1

Respuesta:

-28

Explicación paso a paso:

4(2−5+(−1−2+3)(3)(2−1)−4)

=4(−3+(−1−2+3)(3)(2−1)−4)

=4(−3+(−3+3)(3)(2−1)−4)

=4(−3+(0)(3)(2−1)−4)

=4(−3+0(2−1)−4)

=4(−3+(0)(1)−4)

=4(−3+0−4)

=4(−3−4)

=(4)(−7)

=−28

Comprobación:

4(2−5+(−1−2+3)(3)(2−1)−4)

=(4)(2+−5+(−1−2+3)(3)(2−1)+−4)

=(4)(2)+(4)(−5)+(4)((−1−2+3)(3)(2−1))+(4)(−4)

=8−20+0−16

=−28
