Q. Which of the following is equivalent to the complex number i36 ?Choose 1 answer:(A) 1(B) i(C) −1(D) −i
Definition of i: To solve for i36, we need to remember that i is the imaginary unit, which is defined by i2=−1. We can use the powers of i to simplify i36.
Cycle of powers of i: The powers of i repeat in a cycle: i1 = i, i2 = −1, i3 = -i, and i4 = 1. Then the cycle repeats itself. So, i36 can be simplified by dividing 36 by 4 and looking at the remainder.
Simplifying i36: Divide 36 by 4. The quotient is 9 and the remainder is 0. This means that i36 is the same as (i4)9.
Using the power of i: Since i4=1, then (i4)9=19.
Simplifying to 1:1 raised to any power is still 1, so 19=1.
Final result: Therefore, i36 is equivalent to 1.
