The notation ak meas the matrix a multiplied with itself k times (a) for the n×n diagonal matrices d having enteries dii, tha d2 is also diagonal with enteries dii(b)for the n×n diagonal matrices d what do you think the enteries of dk are?

Step-by-step explanation:

Let A and B be a diagonal matrices.

C=AB is a diagonal matrix. With cii=(aii)(bii) entries.

Then, if D is a diagonal matrix we have:

D2 is a diagonal matrix with entries d2ii=(dii)(dii)=(dii)^2

D3 is a diagonal matrix with entries d3ii=(dii)(dii)(dii)=(dii)^3

....

Dk is a diagonal matrix with entries dkii=(dii)^k

where's the diagrams?
