1.	Let →a=^i+α^j+3^k and →b=3^i−α^j+^k. If the area of the parallelogram whose adjacent sides are represented by the vectors →a and →b is 8√3 square units, then →a⋅→b is equal to
Answer» Let $\to a =^i + α^j + 3^k$ and $\to b = 3^i - α^j +^k$ . If the area of the parallelogram whose adjacent sides are represented by the vectors $\to a$ and $\to b$ is $8 \sqrt{3}$ square units, then $\to a \cdot \to b$ is equal to
