Say you have:(adsbygoogle = window.adsbygoogle || []).push({});

[itex]\frac{\log(x)}{r\log{x}} = y[/itex]

r and y can be any given number.

Is there any way to solve this for x?

ie

[itex]\frac{\log(x)}{1.6\log{x}} = 20[/itex]

I'm getting this because I'm trying to calculate [itex]f(x) = \frac{x}{a}[/itex] where f(x) is of the form [itex]f(x) = cx^r[/itex]

[itex]a > 1[/itex]
