1. TÍNH NHANH:
36.28+36.82+64.69+64.41
36.28 + 36.82 + 64.69 + 64.41 = 36.(28 + 82) + 64.(69 + 41) = 36.110 + 64.110 = (36 + 64).110 = 100.110 = 11000
\(36x28+36x82+64x69+64x41\)
\(=36x\left(28+82\right)+64x\left(69+41\right)\)
\(=36x110+64x110\)
\(=\left(36+64\right)x110\)
\(=100x110\)
\(=11000\)
=36.(28+82)+64.(69+41)
=36.110+64.110
=(36+64).110
=100.110
=11000
