Say I have a function of x, say f(x). Lets say f(x)=c^(x) where c is a constant. I know how to get this x in superscript in excel by going to font and highlighting x, pressing ctr+1, and checking superscript. But say that f(X)=c^[(x+1)^d] where c and d are constants. I could highlight [(x+1)^d] and check superscript. How do I get another superscript so that d appears above (x+1) as a superscript?
