Question

What is the value of x in this simplified expression? (Negative j) Superscript negative 7 = StartFraction 1 Over (negative j) Superscript x EndFraction

Answer 1

Answer:

X=7

Y=5

Step-by-step explanation: In the simplest form they are both opposite of the -7 and -5

Answer 2

Answer:

The value of x is 7.

Step-by-step explanation:

We are given the following in the question:

$-j^{-7} = \dfrac{1}{-j^{x}}$

We have to simplify the above expression to calculate the value of x.

Exponential properties:

$\dfrac{1}{x^a}=x^{-a}$

Simplifying the expression, we get,

$-j^{-7} = \dfrac{1}{-j^{x}}\\\\\Rightarrow -j^{-7} = -j^{-x} \\\Rightarrow x = 7$

Thus, the value of x is 7.
