Matrices - difference M11 as small letters btm and as M^11 i.e ad a power?

So matrices the M11 at btm means 1 x 1 matrix. When the 11 is used as a power do they want you to I'm guessing create a subspace from a larger given matrix e.g 2x2 matrix to 1x1?

    First, when it's on top it's called a superscript, and when it's on the bottom it's a subscript. And like you write ^x for a superscript (or power as you said,) It is recognized that _x means a subscript.

    Can you provide pictures of what you mean though?
