Since we're solving for x, then all the other terms (not containing x) can be simplified to single variables, since they're assumed to be givens. I'll be using p for pi and y for your "funny looking Constant!" symbol. Also: u = b/(3b+1) v = (d/2)^[(3b+1)/b]  y^[(3b+1)/b] w = c/3[(d/2)^3]  y^3 So equation becomes: q/p = uv[x / (2a)]^(1/b)  w uv[x / (2a)]^(1/b) = q/p + w [x / (2a)]^(1/b) = (q + pw) /(puv) x / (2a) = [(q + pw) /(puv)]^b x = 2a[(q + pw) /(puv)]^b CHECK for typos! If you don't like this method, then try your own. Hope you can do the other 2. 2nd one is quite easy, right?

It's an italic lowercase lambda.
