Answer:
-i
Step-by-step explanation:
We are to find the value of i^31
Note that i^2 = -1
Expanding i^31
i^31 =
= (i^2)15 * i
= (-1)^15 * i
= -1 * i
= -i
Hence the equivalent is -i
y = 12/13x - 2/13, characters
Cube? this question is confusing
Do what’s in the brackets first it should be 23/12 or 1 11/12 or 1.916
