See attached file for full problem description.
Please provide proof along with explanation.
For integers n>= 1 and for all real numbers x>=-1, use mathematical induction to prove that 1 + nx =< (1 + x)^n
We first consider the case of n=1:
That is obviously true.
Now let's assume that for some real n=k (k>=1) the inequality holds, i.e.
Mathematical induction is used to provide a proof.
