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

X=7

Y=5

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

Answer 2

The value of x is 7.

Explanation:

We are given the following in the question:

`-j^(-7) = (1)/(-j^(x))`

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

Exponential properties:

`(1)/(x^a)=x^(-a)`

Simplifying the expression, we get,

`-j^(-7) = (1)/(-j^(x))\\\\\Rightarrow -j^(-7) = -j^(-x) \\\Rightarrow x = 7`

Thus, the value of x is 7.
