WebIn a sense, logarithms are themselves exponents. Logarithms have bases, just as do exponentials; for instance, log 5 (25) stands for the power that you have to put on the base 5 in order to get the argument 25.So log 5 (25) = 2, because 5 2 = 25.. But, in all fairness, I have yet to meet a student who understands this explanation the first time they hear it. WebExponential Functions. The term ‘exponent’ implies the ‘power’ of a number. For eg – the exponent of 2 in the number 2 3 is equal to 3. Clearly then, the exponential functions are those where the variable occurs as a power.
