Answer 2

156 x 2 + 156 x 5 + 156 + 156 x 2

= 156 x 2 + 156 x 5 + 156 x 1 + 156 x2

=156 x [ 2 + 5 + 1 + 2 ]

=156 x 10

Chúc học tốt!

Answer 4

156 x 2 + 156 x 5 + 156 + 156 x 2

= 156 x 2 + 156 x 5 + 156 x 1 + 156 x2

=156 x ( 2 + 5 + 1 + 2 )

=156 x 10 

= 1560 

Answer 5

\(156\times2+156\times5+156+156\times2\)

\(=156\times2+156\times5+156\text{​​}\text{​​}\times1+156\times2\)

\(=156\times\left(2+5+1+2\right)\)

\(=156\times10\)

\(=1560\)

Answer 6

=156 x ( 2+5+1+2)

=156 x10

=1560
