\(\text{32.(-39 )+16.(-22 )=-1600}\)

32.(-39)+16.(-22)

=32.(-39)+16.2.(-11)

=32.(-39)+32.(-11)

=32.(-39+-11)

=32.-50

=-1600

   32.(-39)+16.(-22)

= 16.2.(-39)+16.(-22)

= 16.(-78)+16.(-22)

= 16.[(-78)+(-22)]

= 16.(-100)

= -1600

\(32.\left(-39\right)+16.\left(-22\right)=2.16.\left(-39\right)+16\left(-22\right)\)

                                              \(=16.\left(-78\right)+16\left(-22\right)\)

                                              \(=16.\left(-78-22\right)\)

                                              \(=16.\left(-100\right)=-1600\)

-1600 ban nha

\(32.\left(-39\right)+16.\left(-22\right)=16\left(-39.2-22\right)=16.\left(-100\right)=-1600\)

-1600 thì phải

Ta có: \(32.\left(-39\right)+16.\left(-22\right)\)

\(=16.2.\left(-39\right)+16.\left(-22\right)\)

\(=16.\left(-78\right)+16.\left(-22\right)\)

\(=16.\left[\left(-78\right)+\left(-22\right)\right]\)

\(=16.\left(-100\right)\)

\(=-1600\)

\(32.\left(-39\right)+16.\left(-22\right)\)

\(=\left(-1248\right)+\left(-352\right)\)

\(=\left(-1600\right)\)

439296 nha bạn

32.(-39).16.(-22)

= (-1248).16.(-22)

= (-19968).(-22)

= 439296

bạn là Linh lớp 6B à

32.( -39) + 16.( –22)

= 16.2.(-39) + 16.(-22)

= 16.(-78) + 16.(-22)

= 16.[(-78) + (-22)]

= 16.(-100)

= -1600

32.( -39 ) + 16.(-22) = 32.(-39) + 32.(-11)

                             = 32. ( -39  + -11)

                             = 32. -50

                             = -1600

32.(-39)+16.(-22)
