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. WebApr 5, 2024 · The log (x) calculator is an online tool used to find the log of any function to the base 10. It is used to find the logarithm of a number and its alternative forms and integral representations. In mathematics, the concept of logarithm refers to the inverse of exponential functions, or it simply refers to the inverse of multi-valued functions.

WebApr 10, 2024 · We have already seen that every logarithmic equation \({\log}_b(x)=y\) is equivalent to the exponential equation \(b^y=x\). We can use this fact, along with the rules of logarithms, to solve logarithmic equations where the argument is an algebraic expression. For example, consider the equation \({\log}_2(2)+{\log}_2(3x−5)=3\).
