X . 10 = 100                                  ; X + 10 x 10 = 100

       X = 100 : 10                             X + 10 = 100 : 10

       X = 10                                      X + 10 = 10

                                                               X = 10 - 10

                                                               X = 0

x . 10 = 100

x         = 100 : 10

x         = 10

x + 10 × 10 = 100

x + 100        = 100 

x                   = 100 - 100

x                   = 0

a x 100 + b x 10 + c = abc

a x 100 + bc = abc

trả lời chi tiết 

mk cho k!!!!!

x = 15614000 : 100

x = 156140

Bài làm

x.100=15614000

x       =15614000:100

x       =156140.

Hok tốt !

10 x 45 - 25 x 10

= 10 x ( 45 - 25 )

= 10 x 20

= 200

100 x 2 + 100 x 3 

= 100 x ( 2 + 3 )

= 100 x 5

= 500

10 x 45 - 25 x 10 

= 10 x [45 - 25]

= 10 x 20

= 200

100 x 2  + 100 x 3

= 100 x [2 + 3]

= 100 x 5

= 500
