456,32 * 2 * 6 + 9 * 4 * 456,32 + 456,32 * 18 + 456,32 * 7 * 4 + 6 * 456,32

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

= 456,32 * 100

= 45632

456,32 x ( 12+ 36 +18+28+32)

=456,32 x 126

=57496,32

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!

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

= 456,32 x 56
