1. tính nhanh

A= 8 x 12 x 32 + 4 x 27 x 24 + 41 x 6 x 16

Answer 1

8 x 12 x 32 + 4 x 27 x 24 + 41 x 6 x 16

=96 x 32 + 96 x 27 + 96 x 41

=96 x (32 + 27 + 41)

= 96 x 100

=9600

Answer 2

A = 8 × 12 × 32 + 4 × 27 × 24 + 41 × 6 × 16

A = 8 × 12 × 32 + 4 × 24 × 27 + 6 × 16 × 41

A = 96 × 32 + 96 × 27 + 96 × 41

A = 96 × (32 + 27 + 41)

A = 96 × 100

A = 9600

Answer 3

=(8x32)x12+(4x24)x27+(6x16)x41

=96x12+96x27+96x41

=96x(12+27+41)

=96x100

=9600
