ANSWER
y varies inversely as x exponent 4.
EXPLANATION
The inverse variation equation is given as:
[tex]y = \frac{1}{ {x}^{4} } [/tex]
We can see that there is an inverse relation between the quantity y and x.
If the it were [tex]y = \frac{1}{ {x}^2 } [/tex], we say y varies inversely as the square of x.
Hence for the given relation,the precise definition is that, y varies inversely as x exponent 4.
