Answer:  [D]:  " - i " .

Step-by-step explanation:

Note:  " i ³ = \sqrt{-1} .

\sqrt{-1} * \sqrt{-1} * \sqrt{-1} = [ \sqrt{-1} * \sqrt{-1} ] * \sqrt{-1}

                                                             =  {-1}   *  \sqrt{-1}  

                                                             =  -1 \sqrt{-1}
                                                             =    - \sqrt{-1} ;

                                           →  which corresponds to:

                        Answer choice:  [D]:  " - i " .

adelina 88 [10]

Answer:

C:12
