Is e^pi rational? I seem to have heard from one of my tacher that research was going. How far we have gone?
No, e^pi is an irrational number. This means that it cannot be expressed as a ratio of two integers.
No, e^pi cannot be written as a fraction because it is an irrational number.
Euler's number, e, is a transcendental number, meaning it cannot be expressed as a root of a polynomial equation with integer coefficients. When e is raised to the power of a transcendental number, such as pi, the result is also transcendental and thus irrational.
The irrationality of e^pi was proven by Johann Lambert in 1761 using a proof by contradiction. He showed that if e^pi is rational, it would lead to a contradiction in the decimal representation of the number.
The irrationality of e^pi has both mathematical and practical significance. Mathematically, it helps to establish the existence of transcendental numbers, which have important applications in calculus and number theory. Practically, it means that the decimal representation of e^pi is non-repeating and non-terminating, making it useful for generating random numbers in computer programming.
