1.	Let \|A1\|=3,\|A2\|=5, and \|A1+A2\|=5. A1 is same as −→A1 and A2 is same as −→A2. The value of (2A1+3A2).(3A1−2A2) is: (report the magnitude).
Answer» Let $\| \begin{matrix} A_{1} \end{matrix} \| = 3, \| \begin{matrix} A_{2} \end{matrix} \| = 5,$ and $\| \begin{matrix} A_{1} + A_{2} \end{matrix} \| = 5$ . $A_{1}$ is same as $_{1}$ and $A_{2}$ is same as $_{2}$ . The value of $(2 A_{1} + 3 A_{2}) . (3 A_{1} - 2 A_{2})$ is: (report the magnitude).
