Q. Which of the following is equivalent to the complex number i6 i^{6} ?\newlineChoose 11 answer:\newline(A) 11\newline(B) i i \newline(C) 1-1\newline(D) i -i
  1. Step 11: Define ii as the imaginary unit: To solve for i6i^{6}, we need to remember that ii is the imaginary unit, which is defined by the property that i2=1i^2 = -1. We can use this property to simplify i6i^{6}.\newlinei6=(i2)3i^{6} = (i^2)^{3}
  2. Step 22: Simplify i6i^{6} using the property of i2i^2: Now we apply the property that i2=1i^2 = -1.\newline(i2)3=(1)3(i^2)^{3} = (-1)^{3}
  3. Step 33: Apply the property to calculate (1)3(-1)^3: Next, we calculate the value of (1)3(-1)^3.\newline(1)3=1(-1)^3 = -1
  4. Step 44: Determine the value of i6i^{6}: Therefore, i6i^{6} is equivalent to 1-1.
