Question

which number equals ( i^4 )?
options: ( i ), ( 1 ), ( -i ), ( -1 )

Explanation:

Step1: Recuerda la definición de \( i \)

Sabemos que \( i = \sqrt{-1} \), entonces \( i^2 = (\sqrt{-1})^2 = -1 \).

Step2: Calcular \( i^4 \)

Podemos expresar \( i^4 \) como \( (i^2)^2 \). Sustituyendo \( i^2 = -1 \), tenemos \( ( -1 )^2 \).

Step3: Evaluar \( (-1)^2 \)

\( (-1)^2 = 1 \).
