- 4+4i- 4 + 4 \mathrm { i }


A) 42(cos120+isin120) 4 \sqrt { 2 } \left( \cos 120 ^ { \circ } + i \sin 120 ^ { \circ } \right)
B) 42(cos135+isin135) 4 \sqrt { 2 } \left( \cos 135 ^ { \circ } + i \sin 135 ^ { \circ } \right)
C) 16(cos135+isin135) 16 \left( \cos 135 ^ { \circ } + \mathrm { i } \sin 135 ^ { \circ } \right)
D) 16(cos120+isin120) 16 \left( \cos 120 ^ { \circ } + \mathrm { i } \sin 120 ^ { \circ } \right)
