Math Problem Statement
Fie permutările α și β date. Rezolvați ecuațiile xα = β și βy = α^3.
Solution
The image presents a problem involving permutations. The permutations are given as follows:
- Permutation is defined as: \begin{pmatrix} 1 & 2 & 3 & 4 \\ 3 & 4 & 1 & 2 \end{pmatrix}$$ which means $$\alpha(1) = 3$$, $$\alpha(2) = 4$$, $$\alpha(3) = 1$$, and $$\alpha(4) = 2$$.
- Permutation is defined as: \begin{pmatrix} 1 & 2 & 3 & 4 \\ 4 & 2 & 1 & 3 \end{pmatrix}$$ which means $$\beta(1) = 4$$, $$\beta(2) = 2$$, $$\beta(3) = 1$$, and $$\beta(4) = 3$$.
The problem requires solving the equations:
Step-by-step approach:
-
Solve the equation :
- We need to find the permutation such that when it is composed with , it gives .
- This requires finding , where is the inverse of .
-
Solve the equation :
- Here, we are required to find the permutation such that when composed with , it gives .
- This requires , where is the inverse of , and is the cube of the permutation (computed by applying three times).
Let me compute these solutions for you.
