How was this answered? i don't know how, pls. help

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

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
