Inverse matrix
Given a matrix $A$ and its inverse matrix $B$. Choose the correct statements.
We define $I$ as the identity matrix and $A^{T}$ as the transpose of $A$. Further, $k\neq0$ is a scalar and $det(A)$ represents the determinant of A.

Determination of an easy negative power
Write the exact answer to this exercise.
If you need to write the power then use this form a^b. For fractions use this form a/b.
Use this rule to get to the solution:
$ a^{-b\;}=\frac1{a^b}\\ $
1) $ 5^{-2} $
2) $ 7^{-3} $
