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
100x55+100x45x100
=100x(55+45)x10
=100x100x10
=1000x10
=10000
Các bn k mik nha
100*55+100*45*10
=(100*55)+(100*45)*10
=(5500+4500)*10
=10000*10
=100000
=100x10(55+45)
=100x10x100
=1000x100
=100000
