136.(-47)+36.(-304)

48.(-21)-142.(-24)

NHANH NHẤT SẼ TÍCH

Answer 1

\(\left(-48\right)\cdot72+36\left(-304\right)\)

\(=36\left(-48\cdot2-304\right)\)

\(=36\cdot\left(-400\right)\)

\(=-14400\)

Answer 2

\(48\left(-21\right)-142\left(-24\right)\)

\(=24\left[2\left(-21\right)+142\right]\)

\(=24\cdot100\)

\(=2400\)
