WebFirst, visualize our scale as being on a ruler, where each number is 1 cm apart. In a base ten logarithmic scale, 2 cm on the scale corresponds to 10² (100). 3 cm corresponds to 10³ (1000). Obviously, if we change the base of the logarithm, the spacing between each number doesn't matter, it is always one cm between each one. 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.
