Let bold r 1 comma ... Comma bold r subscript pbe vectors in set of real numbers r superscript n, and let q be an m times n matrix. Write the matrix left bracket upper q bold r 1 ...Q bold r subscript p right bracket as a product of two matrices (neither of which is an identity matrix).

Answer and Step-by-step explanation:

Let bold r 1 comma ... Comma bold r subscript p be vectors in the set of real numbers r superscript n:

r1,… ,rp be vector in Rn

And let Q be an m times n matrix = Q= m x n

write the matrix left bracket upper q bold r 1 ...Q bold r subscript p right bracket as a product of two matrices = [Qr1, …, QrP], which is a product of two matrices.

To write the product of two matrices.

Use the definition of AB in reverse order:

[Qr1, …, QrP] = Q [r1, …, rp]

                       = QR
