125 . ( - 24 ) + 24 . 225
= -125.24+24.225
=24.(-125 + 225)
=24.100 = 2400
a) 125.(-24)+24.225
=(-125).24+24.225
=24.[(-125)+225]
=24.100=2400
b) 26.(-125)-125.(-36)
=(-26).125-125.(-36)
=125[(-26)-(-36]
=125.10
=1250
các bạn cho mk vài li-ke cho tròn 980 với
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, \(26\cdot\left(-125\right)-125\cdot\left(-36\right)+125\cdot\left(-7\right)\)

\(=125\cdot\left[\left(-26\right)+36-7\right]\)
\(=125\cdot3\)
\(=375\)
a)125.(-24) + 24.225
= 125. [(-24) + 24].225
= 125.0.225

c) \(C=25\left(75-45\right)-75\left(45-25\right)\)
\(=25.75-25.45-75.45-75.25\)
\(=\left(25.75-75.25\right)-25.45-75.45\)
