Step-by-step explanation:
Subtract 3 everytime
Answer:
see explanation
Step-by-step explanation:
Using
= i, then i² = (
)² = - 1
and i³ = i² × i = - 1 × i = - i
also
= i² × i² = - 1 × - 1 = 1
We can surmise that i raised to any multiple of 4 will equal 1
Given
( note 35 = 32 + 3 and 32 is a multiple of 4 ), thus
= 
= 1 × i³ = - i
