To Steve,

A matrix defined as:
[A B
C D]

to power of 1,000 is not:
[A^1000 B^1000
C^1000 D^1000]

Look at a simpler example of taking this matrix to a similar exponent of 2:
[1 1
1 1]


According to your theory, it will remain the same matrix but it truly is by either doing it manually or via calculator:
[A^2 + BC AC+DC
AB+BD BC+D^2]
=
[2 2
2 2]

Dear Matt,

Another excellent addition to this forum! I would find it hard to calculate manually, but via an online calculator you would get an extremely long answer in which right now looking at, it is very difficult to type out.

You can find it for yourself by plugging the respective values at http://www.hostsrv.com/webmab/app1/MSP/quickmath/02/pageGenerate?site=quickmath&s1=matrices&s2=arithmetic&s3=basic#reply

Or you could ask me to email you the image of the answer directly to your email address.

Sincerely,
Archis
