Proof by induction summation logarithms
Web2 Answers. Hint. Show that log ( k + 1) − log ( k) < ( k + 1) − k. log 2 ( k + 1) < log 2 ( 2 k) = log 2 2 + log 2 k = 1 + log 2 k < 1 + k. The first strict inequality holds whenever k + 1 < 2 k, … WebSep 9, 2024 · Then, the log sum inequality states that. n ∑ i=1ai logc ai bi ≥a logc a b. (1) (1) ∑ i = 1 n a i log c a i b i ≥ a log c a b. Proof: Without loss of generality, we will use the natural logarithm, because a change in the base of the logarithm only implies multiplication by a constant: logca = lna lnc. (2) (2) log c a = ln a ln c.
