If you can
calculate ex then you can
calculate approximations for ln5 using Newton's method... As for ex you can use the Maclaurin series, which converges for any value of x : ex=\u221e\u2211k=0xkk!

The natural log, or ln, is the inverse of e.
The value of e is equal to approximately 2.71828. ... The natural log simply lets people reading the problem know that you're taking the logarithm, with a base of e, of a number. So ln(x) = loge(x). As an example, ln(5) = loge(5) = 1.609.Jan 17, 2020

ln and e cancel each other out. Simplify the left by writing as one logarithm. Put in the base e on both sides. Take the logarithm of both sides.
