WebWorking Together. Exponents and Logarithms work well together because they "undo" each other (so long as the base "a" is the same): They are "Inverse Functions". Doing one, then the other, gets us back to where we started: Doing ax then loga gives us back x: loga(ax) = x. Doing loga then ax gives us back x: aloga(x) = x. WebIf your goal is to find the value of a logarithm, change the base to 10 10 or e e since these logarithms can be calculated on most calculators. So let's change the base of \log_2 (50) log2(50) to {\greenD {10}} 10. To do this, we apply the change of base rule …

Here, the log of 1 to any base is 0, so … WebOne important property of logarithms is that multiplication inside the logarithm is the same thing as addition outside of it. In the same way division is "the same" as subtraction in logarithms. So our expression is the same as. But also, exponents can be moved outside in the same way. is basically , so .
WebNote that unless \(a=e\), we still do not have a mathematically rigorous definition of these functions for irrational exponents. Let’s rectify that here by defining the function \(f(x)=a^x\) in terms of the exponential function \(e^x\). We then examine logarithms with bases other than e as inverse functions of exponential functions.
