Chúc bạn hk tốt nha!

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

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

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

\(=-25.45-75.45\)

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

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