Consider the following matrix A and it's inverse A- 1, O 0 0.5 A = 2 O A- = 1 0 0 (1) O Let the "entry-wise" 7-norm of a m x n matrix B (or vector) be defined as 1/7 m n 1|Bl|7,7 = EEmail? (2) i=1 j=1 Note, this norm is similar to the Euclidean-norm, just replacing the 2 with a 7 in the power and the root. Provide your answers with at least 6 digits. a) By hand, calculate | | A| |7,7. b) By hand, calculate the condition number of A using the "entry-wise" 7-norm
