You want to integrate exp(x), with limits from 1 to b?, and then to find b, such that the integral is 1?
First, how do we perform the integration?
syms x b
int(exp(x),x,[1,b])
ans = 
So that is easy enough. What value of b gives an integral of 1? Just wrap solve around that.
solve(int(exp(x),x,[1,b]) == 1)
ans =
