Find a basis for the row space and the rank of the matrix.−3 1 2 10 6 5−7 5 8(a) a basis for the row space

The question seems to be incomplete. However, I can guide you on how to find a basis for the row space and the rank of a matrix.

Step 1: Write down the matrix. From your question, it seems like the matrix might be a 2x3 matrix, but it's not clear.

Step 2: To find a basis for the row space, you need to reduce the matrix to its row echelon form or reduced row echelon form. You can do this by performing elementary row operations which include swapping two rows, multiplying a row by a non-zero scalar, and adding a multiple of one row to another row.

Step 3: Once you have the row echelon form or reduced row echelon form, the rows that are not zero-rows form a basis for the row space of the matrix.

Step 4: The rank of the matrix is the maximum number of linearly independent rows in the matrix. In the row echelon form or reduced row echelon form, it's simply the number of non-zero rows.

Without the complete matrix, I can't provide a specific answer. Please provide the complete matrix for a more detailed solution.
