Follow along with this tutorial to practice solving a logarithm by first converting it to … WebMay 19, 2015 · May 19, 2015. log100 = 2. To evaluate this you use the definition of a logarithm. logab = c ⇔ ac = b. You also have to assume that if no base b is written then the base is 10. So in the example you have log10100 = c ⇔ 10c = 100. Now you can easily find that c = 2, because 102 = 10 ⋅ 10 = 100. So the answer is. log100 = log10100 = 2. oligarchy date
