1.	If A=⎡⎢⎢⎢⎢⎢⎢⎢⎣2315313234373223⎤⎥⎥⎥⎥⎥⎥⎥⎦ and B=⎡⎢⎢⎢⎢⎢⎢⎢⎣25351152545756525⎤⎥⎥⎥⎥⎥⎥⎥⎦, then compute 3A−5B.
Answer» If $A = ⎡ ⎢⎢⎢⎢⎢⎢⎢ ⎣ \begin{matrix} \frac{2}{3} & 1 & \frac{5}{3} \frac{1}{3} & \frac{2}{3} & \frac{4}{3} \frac{7}{3} & 2 & \frac{2}{3} \end{matrix} ⎤ ⎥⎥⎥⎥⎥⎥⎥ ⎦$ and $B = ⎡ ⎢⎢⎢⎢⎢⎢⎢ ⎣ \begin{matrix} \frac{2}{5} & \frac{3}{5} & 1 \frac{1}{5} & \frac{2}{5} & \frac{4}{5} \frac{7}{5} & \frac{6}{5} & \frac{2}{5} \end{matrix} ⎤ ⎥⎥⎥⎥⎥⎥⎥ ⎦,$ then compute $3 A - 5 B$ .
