Hi I need help with this proof, I don't know if this is correct thanks

c) lim (Rez)" 721 Z-20 Meshod → 0 we have Re z = |2| 2 O≤ (Rez) ² ≤|z| 121 0 ≤ lim (Rez) ² 121 720 <o Now Talling limit on both sides as 2->0. => lim (Rez) ² =0 2-20 121 Methed 2 for I = X GPR, lim (Rez), 3² ZDO 121 EiR, lim (Rez)? Z->0 for Z=y+ing EiR, ✓ -X (Red)" + [²₂ у y 비 y
