k mk nhé chi nguyễn mk kv vs bn rồi

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

a) \(A=125\left(-24\right)+24.225\)

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

\(=24.100=2400\)

b) \(B=26\left(-125\right)-125\left(-36\right)\)

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

\(=125.10=1250\)

c) \(C=25\left(75-45\right)-75\left(45-25\right)\)

\(=25.75-25.45-75.45-75.25\)

\(=\left(25.75-75.25\right)-25.45-75.45\)

\(=-25.45-75.45\)

\(=45\left(-25-75\right)\)

\(=45\left(-100\right)=-4500\)

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

a. 24 x (-125 + 225)

= 24 x 100

       Các câu khác bạn làm tương tự nha

a ) \(125\times\left(-24\right)+24\times225\)

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

\(=24\times100\)

\(=2400\)

b ) \(26\times\left(-125\right)-125\times\left(-36\right)\)

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

\(=125\times10\)

\(=1250\)

a)125.(-24) + 24.225

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

= 125.0.225

= 0.

a: =34x(-100)=-3400

b: =41(-76-24)=-4100

c: =-24(125-225)=2400

d: =26(-237+137)=-2600

e: =25(-63+23)=25x(-40)=-1000

1/  11.(-36) - 64 . 11

    = 11 ( -36-64)

     = 11 x (-100) =-1100

2/  125 x (-24+24)

      = 125 x 0 =0

3/  -125 x 23 + 23 x 225

     = 23 ( -125 + 225)

      = 23 x 100 = 2300

(-11)(36+64)=-11.100=-1100

125(-24+24)=125.0=0

-23(125-225)=-23.(-100)=2300
