a, \(125\times\left(-24\right)+24\times255=3120\)

\(b,26\times\left(-125\right)-125\times\left(-36\right)=1250\)

a=2400

b=1250

a)125.(-24) + 24.225

= 125. [(-24) + 24].225

= 125.0.225

= 0.

1. Tính nhanh:

a) \(125.\left(-24\right)+24.225\)

= \(-125.24+24.225\)

\(=24\left(-125+225\right)\)

\(=24\) . \(100\)

= \(2400\)

b) \(26.\left(-125\right)-125.\left(-36\right)+125.\left(-7\right)\)

\(=-26.125-125.\left(-36\right)+125.\left(-7\right)\)

\(=125\left[-26-\left(-36\right)+\left(-7\right)\right]\)

\(=125.3\)

\(=375.\)

a, \(125\cdot\left(-24\right)+24\cdot225\)

\(=\left(-125\right)\cdot24+24\cdot225\)

\(=24\cdot\left[\left(-125\right)+225\right]\)

\(=24\cdot100\)

\(=2400\)

b, \(26\cdot\left(-125\right)-125\cdot\left(-36\right)+125\cdot\left(-7\right)\)

\(=\left(-26\right)\cdot125-125\cdot\left(-36\right)+125\cdot\left(-7\right)\)

\(=125\cdot\left[\left(-26\right)+36-7\right]\)

\(=125\cdot3\)

\(=375\)

nhanh lên giúp mình với
