You can put this solution on YOUR website!
Why, and not showing any y variable, how? You should want to simplify your expression.

81%5E%28log%289%2C8x%29%29

%289%5E2%29%5Elog%289%2C%288x%29%29

The site's rendering might not give a good display, but continuing,...

9%5E%282%2Alog%289%2C%288x%29%29%29

9%5E%28log%289%2C%288x%29%5E2%29%29
Next, because exponential function and log function are inverses, their composition will be their input:

%288x%29%5E2

highlight%2864x%5E2%29
