Q. Which of the following is equivalent to the complex number i20 ?Choose 1 answer:(A) 1(B) i(C) −1(D) −i
Definition of i: To solve for i20, we need to remember that i is the imaginary unit, which is defined by i2=−1. We can use this property to simplify i20.i20=(i2)10=(−1)10
Simplifying i20: Since (−1)10 is raising −1 to an even power, the result will be 1.(−1)10=1
Result of i20: Now we have found that i20 is equivalent to 1, which matches one of the given choices.
