The question asks to evaluate the expression involving three constants: $\phi$ (phi), $e$, and $\pi$.

• $\phi$ (phi) is the golden ratio, approximately $1.618$.
• $e$ is Euler's number, approximately $2.718$.
• $\pi$ is pi, approximately $3.141$.

The sum of these constants is:

$\phi + e + \pi = 1.618 + 2.718 + 3.141$

Let's calculate the total sum.The sum of the constants $\phi + e + \pi$ is approximately $7.477$.
