Evaluate a Natural Logarithm Without a Calculator

👉 Learn how to evaluate natural logarithms. Recall that the logarithm of a number says a to the base of another number say b is a number say n which when raised as a power of b gives a. (i.e. log [base b] (a) = n means that b^n = a). Natural logarithms (ln or log to base e) are simply logarithms whose base is the exponential (e). The natural logarithm obeys all the properties of the regular logarithms. To evaluate natural logarithms, we either rewrite the expression as an exponential equation using the definition of a logarithm or evaluate using properties of logarithms.

🌟 Very Good Brian McLogan, Keep It Up! 🌟

It's always important to evaluate a natural log once a day. Coffee and a bran muffin definitely helps

thanks! i finally understand this lesson without using a calc

I'm brazilian, thanks for your lesson, very gratefully....

thanks for the lesson but i have a question how can i calculate ln(9) without using a calculator

[stoplookin]

I understand these types of problems and how to get to the correct answer, but instead of doing the same routine over again without actually thinking, I'd like to actually know how I got the answer. Why exactly does ln(base) e and e both cancel out? Instead of just being a robot and solving these types of questions without really thinking, I'd like to know why exactly I do the steps that I do. Are ln(base) e and e inverses or something?
