2022 PEA Q26

Let AA be a specified 6×86 \times 8 (or square, source unclear) matrix [the entries of AA were not legibly transcribed in the source]. Which one is an eigenvalue of AA?

Reveal answer and solution

Solution

  1. 1

    The matrix AA is not provided in a usable form (the source describes only a ``Large 6×86\times8

  2. 2

    matrix''). Eigenvalues are defined only for square matrices, so the dimension itself is

  3. 3

    unclear. Without the precise entries of AA we cannot uniquely determine which of {1,2,3,5}\{1,2,3,5\}

  4. 4

    is an eigenvalue.
