Answer:
The value of x is 7.
Step-by-step explanation:
We are given the following in the question:
[tex]-j^{-7} = \dfrac{1}{-j^{x}}[/tex]
We have to simplify the above expression to calculate the value of x.
Exponential properties:
[tex]\dfrac{1}{x^a}=x^{-a}[/tex]
Simplifying the expression, we get,
[tex]-j^{-7} = \dfrac{1}{-j^{x}}\\\\\Rightarrow -j^{-7} = -j^{-x} \\\Rightarrow x = 7[/tex]
Thus, the value of x is 7.
Answer:
