Hey,

You can use the following code to search numerically as I don't think this equation can be solved analytically.

eq=16^(x^2+y)+16^(y^2+x)-1;
Plot3D[eq==0,{x,-2,1},{y,-2,1}]
FindRoot[(eq/.x->-1/2)==0,{y,-1/3}]
Manipulate[ContourPlot[eq==a,{x,-2,1},{y,-2,1}],{{a,1},0,5,0.1}]

I won't put my hand in the fire, but I think that your equation is satisfied only by one point. If you change the constant, then you can plot the contours.

Cheers
