] | Let $n \ge 1$. Since $2$ is the first prime, our product is even. Thus $p\_1\cdots p\_n+1$ is odd. Suppose it is equal to the odd perfect square $m^2$.
Note that $m^2-1$ is divisible by $4$, indeed by $8$. But $p\_1\cdots p\_n$ is not divisible by $4$. Thus $p\_1\cdots p\_n+1$ cannot be a perfect square.
