1.	If z1,z2,z3 are complex numbers such that \|z1\|=\|z2\|=\|z3\|=∣∣1z1+1z2+1z3∣∣=1, then \|z1+z2+z3\| is
Answer» If $z_{1}, z_{2}, z_{3}$ are complex numbers such that $\| z_{1} \| = \| z_{2} \| = \| z_{3} \| = ∣ ∣ \frac{1}{z_{1}} + \frac{1}{z_{2}} + \frac{1}{z_{3}} ∣ ∣ = 1$ , then $\| z_{1} + z_{2} + z_{3} \|$ is
