logarithm mathematical constant. The value of e is equal to approximately 271828. In this definition y logbx y log b x is called the logarithm form and by x b y x is called the exponential form.
For example 2 3 8. It is log to the base of e. Log_blueD b goldD agreenD cquad iffquad blueD bgreenD cgoldD a logb a c bc a.
Like p e is a mathematical constant and has a set value.
The natural logarithm of x is generally written as ln x loge x or sometimes if the base e is implicit simply log x. The letter e represents a mathematical constant also known as the natural exponent. In other words if we take a logarithm of a number we undo an exponentiation. In other words log e x ln x.
