Let's say I want to plot a function $f(x,y)= x^3 y^3 + e^{-x}$ using 3D plot; x runs from 0.00001 to 0.1 and y runs from 1 to 100. Now, I want to have a logarithmic scale along the x-axis. So, how to do that?

I used the following command for 3D plot:

Plot3D[x^3 y^3 + Exp[-x], {x, 0.00001, 0.1}, {y, 1, 100}]

As mentioned by Carl Woll in comments, the easiest way it to use the ScalingFunctions option to Plot3D:

Plot3D[
  x^3 y^3 + Exp[-x], {x, 0.00001, 0.1}, {y, 1, 100},
  ScalingFunctions -> {"Log", None, None},
  PlotRange -> All, AxesLabel -> Automatic
]

Try

ParametricPlot3D[{Log[x], y, x^3 y^3 + Exp[-x]},{x, 0.00001,0.1}, {y, 1, 100}, BoxRatios -> 1]
