Question

cuanto es [ ( 1 7 − 1 5 ) 3 + ( 7 − 1 2 ) 2 ] : [ ( 6 − 7 ) · ( 1 2 − 2 3 ) ] es para hoy con proceso por fa

Answer 1

la primera = 1)(7)−(1)(5))(3)+(7−(1)(2))(2)

=(7−(1)(5))(3)+(7−(1)(2))(2)

=(7−5)(3)+(7−(1)(2))(2)

=(2)(3)+(7−(1)(2))(2)

=6+(7−(1)(2))(2)

=6+(7−2)(2)

=6+(5)(2)

=6+10

=16

la segunda= (6−7)((1)(2)−(2)(3))

=−1((1)(2)−(2)(3))

=−1(2−(2)(3))

=−1(2−6)

=(−1)(−4)

=4
