Question

1. TÍNH NHANH:

36.28+36.82+64.69+64.41

Answer 1

36.28 + 36.82 + 64.69 + 64.41 = 36.(28 + 82) + 64.(69 + 41) = 36.110 + 64.110 = (36 + 64).110 = 100.110 = 11000 

Answer 2

\(36x28+36x82+64x69+64x41\)

\(=36x\left(28+82\right)+64x\left(69+41\right)\)

\(=36x110+64x110\)

\(=\left(36+64\right)x110\)

\(=100x110\)

\(=11000\)

Answer 3

=36.(28+82)+64.(69+41)

=36.110+64.110

=(36+64).110

=100.110

=11000
