How do you write an e function?

Fixing b=e, we can write the exponential functions as f(x)=ekx. (The applet understands the value of e, so you can type e in the box for b.) Using e for the base is so common, that ex (“e to the x”) is often referred to simply as the exponential function.

How do you write in base e?

The logarithm that uses the number e as its base is called the natural logarithm. You write it as ln(x) or log sub e (x). Some calculations that are easy to remember include ln(e) = 1 and ln(1) = 0. The inverse of the natural log is e^x.

What are the laws of e function?

The first law states that to multiply two exponential functions with the same base, we simply add the exponents. The second law states that to divide two exponential functions with the same base, we subtract the exponents. The third law states that in order to raise a power to a new power, we multiply the exponents.
