If a is a diagonalizable matrix, a) prove that a^t is diagonalizable. b) prove that a^-1 is diagonalizable. c) prove that a^2 is diagonalizable. d) prove that a^k is diagonalizable for any positive integer k.

11

step-by-step explanation:

32.50-7.50=25

225/25=11

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
