    Bernoulli's Inequality

    I don't even know how to begin this problem. Induction maybe?

    Prove: If a in R,
    a does not = 0,
    a > -1

    Then: for all k in N, [ (1+a)^k+1 ] > [ 1 + (k+1)a ].

    still stuck

    I see the equations are slightly different. But I'm still having a litte trouble. Do I prove it true for a,k=1
    then in the inductive step prove it true for a=a+1 and k=k+1?
