Question

−40{−80[30(−40 + 80) − 60(85 − 40)] − 90(−60 + (−85))}

Answer 1

Respuesta:

−40(−80(30(−40+80)−60(85−40))−90(−60−85))

=−40(−80((30)(40)−60(85−40))−90(−60−85))

=−40(−80(1200−60(85−40))−90(−60−85))

=−40(−80(1200−(60)(45))−90(−60−85))

=−40(−80(1200−2700)−90(−60−85))

=−40((−80)(−1500)−90(−60−85))

=−40(120000−90(−60−85))

=−40(120000−(90)(−145))

=−40(120000−(−13050))

=(−40)(133050)

=−5322000
