Question
The solution for the system of post correspondence problem, $A=\{b a, a b b, b a b\}, B=\{b a b, b b, a b b\}$ is(A) 1312212(B) 15234434(C) 1311322(D) No solution.
Step 1
The Post Correspondence Problem (PCP) is a well-known undecidable problem in computer science and mathematical logic. It asks whether there exists a sequence of choices of tiles from two given sets (in this case, sets A and B) such that the sequence of letters on Show more…

The system of equations $a x+b y+c z+d=0$ $-b x+a y-d z+c=0$ $-c x+d y+a z-b=0$ $-\mathrm{dx}-\mathrm{cy}+\mathrm{bz}+\mathrm{a}=0$ for real non-zero values of $\mathrm{a}, \mathrm{b}, \mathrm{c}, \mathrm{d}$ is (a) consistent and trivial solution (b) consistent and infinitely many solution (c) consistent and non trivial solution (d) not consistent
If $|a|=|b|$ and $\overrightarrow{a c} \neq b \bar{c}$, then the equation $a z+b \bar{z}+$ $c=0$ has (a) no solution (b) exactly one solution (c) finitely many solutions (d) infinitely many solutions
