A quality control technician in an electronics factory is calculating the phase angle of a signal represented by the power of the imaginary unit $i^{86}$. Based on the properties of $i$, what is the simplified value of $i^{86}$?

A laboratory technician is documenting the process for simplifying calculations involving complex numbers in a circuit design report. Arrange the following steps in the correct logical order to simplify the expression $i^{86}$ to its simplest form.

A quality control technician at an electronics manufacturing plant is documenting a phase-shift test. The test result is recorded as the complex power $i^{86}$. To simplify the report for a data entry system that only accepts real numbers, the technician must convert this expression to its simplest form. The simplified value of $i^{86}$ is ____.

A student is preparing a technical report on complex numbers for an electronics class. The student needs to simplify the expression $i^{86}$ to its most basic form. Match each component of the simplification process used by the student with its correct value.

An engineering apprentice at a telecommunications company is reviewing a legacy code snippet for a signal processing algorithm. The documentation claims that the phase shift term represented by $i^{86}$ simplifies to $-1$.
