i. X x a = aa k. ab x X = abab m. abc x X = abcabc n.ab0ab0 : X = ab
X = aa : a X = abab : ab X = abcabc : abc X = ab0ab0 : ab
X = 11 X = 101 X = 1001 X = 10010
11 x a = aa
ab x 1111 = abab
abc x 111111 = abcabc
aboabo : 111111 = ab
i, X= aa:a
X=11
k,X=abab:ab
X=101
m,X=abcabc:abc
X=1001
câu cuối m chưa lm đk b nhé
n. ab0ab0: X=ab =>X=ab0ab0:ab =>X=1010
aboabo =100000+10000 + 100 +10 =110110
ab= 10 + 1 =11
aboabo : x = ab
aboabo = 100000+ 10000 + 100 + 10 = 110110
ab= 10 + 1 = 11
x = aboabo : ab = 110110 : 11 = 10010
