Q. Which of the following is equivalent to the complex number i32 ?Choose 1 answer:(A) 1(B) i(C) −1(D) −i
Understand Powers of i: To find the equivalent of i32, we need to know the pattern of powers of i. The powers of i repeat in a cycle of 4: i1=i, i2=−1, i3=−i, and i4=1. After i4, the cycle repeats.
Simplify i32: Since the powers of i repeat every 4 steps, we can simplify i32 by dividing 32 by 4. The remainder of this division will tell us the equivalent power of i within the first cycle of 4.
Calculate i4×8: Divide 32 by 4: 32÷4=8. Since there is no remainder, i32 is equivalent to i4×8, which is (i4)8.
Find Equivalent of i4: We know that i4=1. Therefore, (i4)8=18.
Calculate 18: Calculate 18: 18=1, because any non-zero number raised to any power is itself.
Conclude i32: Since 18=1, we conclude that i32 is equivalent to 1.
