For part (a), a diagonalization of A is
A = PDP-¹ –
-1 1692
1/3 1/3
-2/3-1/3
SO
A100

= PD¹00p-1
5100 +2
32(51001) 2.5100+1
5100 1
(Remember that (-1)100 is just 1, so there's no reason to have the expression (-1)100 in the final, simplified
answer). For part (b), a diagonalization of B is
B = PDP-¹ _
FARINA.

B50 PD50p-1 _
[2.350 250 251 2.350]
350 - 250 251 - 350
The matrices P and D in your diagonalizations may be different (you may have listed the eigenvalues in the
other order on the diagonal of D, or chosen different scalar multiples for your eigenvectors as the columns
of P), but your final answers must be the same as mine (any differences "cancel out" after multiplying by
P-¹, since changing P changes P-¹ as well).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffa923b6f-81dd-482c-8885-6de6bc295751%2Fb0651d90-3601-4665-a879-4ebfea11fb87%2Fdew0pyi_processed.jpeg&w=3840&q=75)

You must show all steps for this problem. Simplify your final answers; these answers should be single 2 × 2
matrices, not products of several matrices. (You are allowed to leave numbers of the form n100 or n
that form, of course!)
