# Zero's of zeta function

In an article it is given that,
[HR][/HR]
$$\displaystyle \zeta(s)=\text{exp} (\sum_{n=1}^\infty\frac{\Lambda{(n)}}{\text{log}(n)}n^{-s})$$​
[HR][/HR]
$\zeta(s)$ has pole at $s=1$ and zeroes at several $s=\rho$.
here i think he considered the function inside the exponential rather than whole exponential to obtain poles and zeroes but I think we should consider it along with exponential or can we?.Or does he consider the entire function if so how does it have pole at s=1 and zeroes at $$\displaystyle s=\rho$$
what are those several $\rho$'s?
