Question

If A^T = `[(4, 5),(-1, 0),(2, 3)]` and B = `[(2, -1, 1),(7, 5, -2)]`, veriy the following 

(B^T)^T = B

Answer 1

A^T = `[(4, 5),(-1, 0),(2, 3)]` and B = `[(2, -1, 1),(7, 5, -2)]`

B^T = `[(2, 7),(-1, 5),(1, -2)]`

(B^T)^T = `[(2, 7),(-1, 5),(1, -2)]^"T"`

(B^T)^T = `[(2, -1, 1),(7, 5, -2)]`

(B^T)^T = B
