What is the value of i^97?

To find the value of i97, we first need to understand the behavior of the imaginary unit, i, which is defined as the square root of -1. The powers of i follow a cyclical pattern:

  • i1 = i
  • i2 = -1
  • i3 = -i
  • i4 = 1

After i4, the pattern repeats:

  • i5 = i
  • i6 = -1
  • i7 = -i
  • i8 = 1

This cycle continues every four powers: i, -1, -i, 1. To determine the value of i97, we need to find the remainder of 97 when divided by 4:

97 ÷ 4 = 24 remainder 1

This tells us that i97 corresponds to i1 in our cycle. Therefore:

i97 = i
