Tính nhanh: 125*(-26)+26*(-25)

Answer 1

125.(-26)+26.(-25)

= -125.26+26.(-25)

= [-125+(-25)].26

= -150.26

Answer 2

\(125.\left(-26\right)+26.\left(-25\right)\)

\(=\left(-125\right).26+26.\left(-25\right)\)

\(=26.\left[\left(-125\right)+\left(-25\right)\right]\)

\(=26.\left(-150\right)\)

\(=-3900\)

Answer 3

\(125.\left(-26\right)+26.\left(-25\right)\)

\(=\left(-125\right).26+26.\left(-25\right)\)

\(=26.\left(-125\right)+\left(-25\right)\)

\(=26.\left(-150\right)\)

\(=-3900\)
