If i=1, what is the value of 1³? O -1 Oi 0 1 O-i
2 answers:
Answer: [D]: " - i " .
Step-by-step explanation:
Note: " i ³ = .
\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 " .
