Logarithms and Natural Logarithms and Eulers Constant (e) Calculator

This calculator does the following:
* Takes the Natural Log base e of a number x Ln(x) → log_ex
* Raises e to a power of y, e^y
* Performs the change of base rule on log_b(x)
* Solves equations in the form b^cx = d where b, c, and d are constants and x is any variable a-z
* Solves equations in the form ce^dx=b where b, c, and d are constants, e is Eulers Constant = 2.71828182846, and x is any variable a-z
* Exponential form to logarithmic form for expressions such as 5³ = 125 to logarithmic form
* Logarithmic form to exponential form for expressions such as Log₅125 = 3

This calculator has 1 input.

1. Ln(a/b) = Ln(a) - Ln(b)
2. Ln(ab)= Ln(a) + Ln(b)
3. Ln(e) = 1
4. Ln(1) = 0
5. Ln(x^y) = y * ln(x)
