Consider for example the expression
expr:x^g(x^(b+1/b));
How to ratsimp subexpression b+1/b ?
I tried
ratsimp(expr), ratsimpexpons:true
but don't work (I expect something as x^g(x^((b^2+1)/b))) )
For simple example expr: g(x^(b+1/b))
rat(expr), ratsimpexpons:true
work as expected but not ratsimp(expr), ratsimpexpons:true (why?)
