To find the value of i97, let’s first clarify what the imaginary unit i is. The imaginary unit i is defined as the square root of -1. When we raise i to various powers, it follows a recurring pattern:
- i1 = i
- i2 = -1
- i3 = -i
- i4 = 1
This pattern repeats every four powers, which means for higher powers of i, we can use the modulus of the power with respect to 4 to simplify our calculations. In this case, we need to find 97 modulo 4:
97 ÷ 4 = 24 with a remainder of 1.
Since the remainder is 1, we can say:
i97 = i(4 * 24) + 1 = (i4)24 * i1 = 124 * i = i
Thus, the value of i raised to the 97th power is:
Result: i
This shows that i97 is simply equal to i.
