. For each space find the matrix changing a vector representation with respect to B to one with respect to D. (a) V = R³, B = ε3, D = 2 0 3 (b) VR³, B = (2 ), D = E3 (c) V = P2, B = (x², x² + x, x² + x + 1), D = (2, −x, x²)

Determine if the statement is true or false. If the statement is false, then correct it and make it true. For the product of two matrices to be defined, the number of rows of the first matrix must equal the number of columns of the second matrix.

Find two 22 matrices such that |A|+|B|=|A+B|.
