Answer:

k=100, n=3, 1.5625, 10

Explanation:

To find n and k, we can plug x and z in.

First we can try this for (1,100). We will get:


100=(k)/(1^(n) )

Since 1 to any power is 1, we can assume that the denominator is 1 and therefore k=100.

Armed with k=100, we can plug numbers into the second equation.


12.5=(100)/(2^(n) )

Moving
{2^(n) } to the left side, we get:


2^n=(100)/(12.5) }=8

therefore we can solve and we see that n=3.

We can do the same for x=4, but since we have n, k, and x, we can plug these in to get z


z=(100)/(4^(3)) =1.5625

We will do the same as previous but instead plug in x


(1)/(10)=(100)/(x^(3) )

We isolate
x^(3) and get


x^(3) =1000

Therefore x=10
