Question

va rog sa ma ajutati la ex. 10

Answer 1

a)
aba, unde a ×b ×a = 4
141, 1×4×1 = 4
212, 2×1×2 = 4
b )
abcabc, unde a +b+c+a+b+c = 6
102102, 1+0+2+1+0+2 = 6
120120, 1+2+0+1+2+0 = 6
201201, 2+0+1+2+0+1 = 6
210210, 2+1+0+2+1+0 = 6

Answer 2

aba =  a x b x a

212      2 x 1 x 2

141       1 x 4 x 1

abcabc = a + b + c + a + b + c

102102     1 + 0 + 2 + 1 +0 + 2

120120 sau 210210 sau 201201
