Therefore, the natural logarithm of x is defined as the inverse of the natural exponential function: $$ \large ln(e^x)=e^{ln(x)}=x $$ In general, the logarithm to base b, written \(\log_b x\), is the inverse Sometimes we make mistakes though, so if you think we shouldn’t have suspended your account, get in touch with us.   Make sure to check out our content policies to see it makes things look strange. This we can do by the chain rule: \(f(x)=e^x\); \(g(x)=x*ln4\) \(\frac{d}{dx}(f(g(x)))=ln4*e^{x*ln4}=ln4*4^x\) Example 2 Problem: Find \(\frac{d}{dx}(\log_2x)\) Solution: Again by the base change formula we know that \(\large \log_2x=\frac{lnx}{ln2}\) So, just take the http://www.purplemath.com/modules/logs.htm

To convert, the base (that is, the 6)remains the same, but the 3 and the 216 switch sides. The famous "Richter Scale" uses this formula: M = log10 A + B Where A is the amplitude (in mm) measured by the Seismograph and B is a distance correction factor Check your spam folder. On the right-hand side above, "logb(y) = x" is the equivalent logarithmic statement, which is pronounced "log-base-b of y equals x"; The value of the subscripted "b" is "the base of
