1. The problem statement, all variables and given/known data Let 0< r <1. If x>0 or -1 less than or equal x <0. SHOW THAT (1+x) ^ r <1+rx 2. Relevant equations no relevant equations 3. The attempt at a solution I've tried isolating, but I can't relate x to x or r to r. I can't split the equation because I don't know r.
