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. WebAlgebra. Evaluate log base 2 of 32. log2 (32) log 2 ( 32) Rewrite as an equation. log2(32) = x log 2 ( 32) = x. Rewrite log2 (32) = x log 2 ( 32) = x in exponential form using the definition of a logarithm. If x x and b b are positive real numbers and b b does not equal 1 1, then logb (x) = y log b ( x) = y is equivalent to by = x b y = x.
