Answer
$\frac{1}{k^4}$
Work Step by Step
We start with the given expression: $k^{-4}j^0$.
The negative exponent rule states that for every nonzero number $a$ and integer $n$, $a^{-n}=\frac{1}{a^n}$.
We use the rule to rearrange the expression as follows: $\frac{j^0}{k^4}$.
The zero as an exponent rule states that for every nonzero number $a$, $a^0=1$.
We use the rule to simplify the expression as follows: $\frac{1}{k^4}$
