I Applying the natural logarithm function to both sides of the equation ex 4 = 10, we get ln(ex 4) = ln(10) I Using the fact that ln(eu) = u, (with u = x 4) , we get x 4 = ln(10); or x = ln(10) + 4: Annette Pilkington Natural Logarithm and Natural Exponential Therefore, ln x = y if and only if e y = x . Common and Natural Logarithms We can use many bases for a logarithm, but the bases most typically used are the bases of the common logarithm and the natural logarithm. Proof. • Then ln(xy) = lnx+lny +C for some constant C. At x = 1, both sides take the same value of lny, thus C = 0.
