Answer 1

Respuesta:

Explicación paso a paso:

-1+(18:9-12:4).2-15.(32:8-2.3)=

=−1+(2− 12 /4 )(2)−15( 32 /8 −(2)(3))

=−1+(2−3)(2)−15( 32 /8 −(2)(3))

=−1+(−1)(2)−15( 32 /8 −(2)(3))

=−1+−2−15( 32 /8 −(2)(3))

=−3−15( 32 /8 −(2)(3))

=−3−15(4−(2)(3))

=−3−15(4−6)

=−3−(15)(−2)

=−3−(−30)

=27

-49:7+(18:2-21:3).3+56:(-8) ​

=−7+( 18 /2 − 21 /3 )(3)+ 56 /−8

=−7+(9− 21 /3 )(3)+ 56 /−8

=−7+(9−7)(3)+ 56 /−8

=−7+(2)(3)+ 56 /−8

=−7+6+ 56 /−8

=−1+ 56 /−8

=−1+−7

=−8
