456,32*2*6+9*4*456.32+456,32*18+456.32*7*4+6*456.32.tinh bang cách thuận tiện 

Answer 1

Nhìn hơi rối mắt:

\(456.32x2x6+9x4x456.32+456.32x18+456.32x7x4+6x456.32\)

\(=456.32x12+36x456.32+456.32x18+456.32x28+6x456.32\)

\(=456.32x\left(12+36+18+28+6\right)\)

\(=456.32x100\)

\(=45632\)

Nhớ k mk nha mk tuyệt vọng lắm rồi!

Answer 2

= 456,32 x ( 2 + 6 + 9 + 4 + 18 + 7 + 4 + 6 )
