Answer 3

1x2x25x8x6x125

=(2x25)x(8x125)x6x1

=50x1000x6

=300000

Answer 4

1x2x25x8x6x125

=(125x8)x(25x8)x6x2x1

=1000    x 200   x 12

=2400000

chúc bn học tốt !

Answer 5

tính nhanh : 1 x 2 x 25 x 8 x 6 x 125 

              \(=2.5^2.2^3.2.3.5^3\)

                \(=2^5.5^5.3\)

                  \(=\left(2.5\right)^5.3\)

                \(=10^5.3\)

                   \(=300000\)
