Weblog base a of b = M. then I can write b = a^M by the definition of the logarithm. Now take the natural logarithm (or other base if you want) of both sides of the equation to get the equivalent equation ln(b)=ln(a^M). Now we can use the exponent property of logarithms we proved above to write ln(b)=M*ln(a). Divide both sides by ln(a) to get Web2. A cool rule about logarithmic functions is that. a ⋅ log b ( x) = log b ( x a). From this, 10 4 log ( x) = 10 log ( x 4).
