4 times pi squared

is this number transcendental?
Thanks from manus

Yes, of course. If it were not it would satisfy a polynomial equation, say nth degree, with integer coefficients. But since any integer power of 4 is an integer that would then give a polynomial equation, of degree 2n, with integer coefficients, satisfied by $\displaystyle \pi$,which is impossible because $\displaystyle \pi$ is transcendental.
Thanks from 123qwerty and manus

Seriously? Since you simply asked whether a specific number was "transcendental", I assumed you knew what "transcendental number" meant! Are you now saying that you do not?

A number, a, is "transcendental" if and only there exist a polynomial equation with integer coefficients (equivalently "rational coefficients") having a as a root. If a3 were NOT transcendental, then there would exist a Polynomial, of degree n, having a/3 as a root. Then that same polynomial, multiplied by 3 to the nth power, would have x as a root showing that a is not transcendental.

This should have been "if and only if there does not exist...", of course.
