Practice problem
Your original matrix was [452682703511]\begin{bmatrix}4&5&2&6\\8&2&7&0\\3&5&1&1\end{bmatrix}483525271601 and you now have [827045263511]\begin{bmatrix}8&2&7&0\\4&5&2&6\\3&5&1&1\end{bmatrix}843255721061. What row operation was performed?
R0⟷R2R_0\longleftrightarrow R_2R0⟷R2
R2⟷R3R_2\longleftrightarrow R_3R2⟷R3
R1⟷R3R_1\longleftrightarrow R_3R1⟷R3
R1⟷R2R_1\longleftrightarrow R_2R1⟷R2
Type a concept, like “slope” or “photosynthesis”.
