x : 10 x 10 = 100
x : 100 = 100
x = 100 x 100
x = 10 000
x:10=100:10
x:10=10
x=10*10
x=100
vậy x=100
x:10.10=100
x:100=100
x=100.100
x=10000
k nhé
x : 10 x 10 = 100
x : 10 = 100 : 10
x : 10 = 10
=> x = 100.
x : 10 x 10 = 100
x : 100 = 100
x = 100 x 100
x = 10 000
x / 10 * 10 = 100
x = x / 100 = 100
x = 100 * 100
x = 10000
X : 10 x 10 = 100
X : 100 = 100
X = 100 x 100
X = 10000
