Answer 1

tính bằng cách thuận tiện nhất :

100 x 55 + 100 x 45 x 10

= 100 x 55 + 100 x 45 x 10

= 100 x 55 + 100 x 450

= 100 x ( 55 + 450 )

= 100 x 500

= 50000

Answer 2

100x55+100x45x100

=100x(55+45)x10

=100x100x10

=1000x10

=10000

       Các bn k mik nha

Answer 3

100*55+100*45*10

=(100*55)+(100*45)*10

=(5500+4500)*10

=10000*10

=100000

Answer 4

=100x10(55+45)

=100x10x100

=1000x100

=100000

Answer 5

=(55+45)x100x10
