Question 02 (d) 

Consider the matrix
(d) Find a basis for the row space of A. 
Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you? 
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it!

Please rate my easiness! It's quick and helps everyone guide their studies. From part (a), we found that We know that the basis of i.e columns of corresponding to the pivot columns of , is the same as the pivot rows of . The pivot rows of are row 1 and 2. Therefore a basis of R(A^{T}) is given by
