Answer 1

Answer:

Hey mate here is your answer

$( \frac{ - 1}{a} \: \: \: \: \frac{1}{b} ) \times ( \frac{ - 1}{a} \: \: \: \: \frac{1}{b})$

mate this multiplication is not possible because for multiplication the number of rows must be equal to the number of columns

The size of the first matix is 1×2

For multiplication the order of 2nd matrix must be 2×1
