WebJun 21, 2024 · Divide the result by the value log c ( a). Inverting this operation produces the rule. Multiply the input by the value X (for some X ). So we want something that looks like. a b = c ( b X) Well, it turns out that X = log c ( a) is the correct value. So this really is the ` Change of Base' formula for exponential functions. Share. WebNov 16, 2024 · The change of base formula is, \[{\log _b}x = \frac{{{{\log }_a}x}}{{{{\log }_a}b}}\] This is the most general change of base formula and will convert from base \(b\) to base \(a\). However, the usual reason for using the change of base formula is to compute the value of a logarithm that is in a base that you can’t easily deal with. Using the ...
