WebOct 11, 2024 · Since f ( x) = log x is monotonically increasing ( x > 0) and log 1 = 0, when the base is less than 1, log b is negative and you will need to flip the sign. By the change of base formula, this is equivalent to: n log ( 1 2) ( 1 2) > log ( 1 2) ( 1 4) n > 2 as you have already said.
