The Greek letter iota, i, represents the square root of -1 (). We call i an imaginary unit. Any number that is a product of a re
al number and the imaginary unit i is called an imaginary number. Complex numbers are numbers that consist of a real part and an imaginary part. They are generally expressed as a + bi. In this task, you will find a pattern relating to the powers of i and also discover some identities involving complex numbers. Use the identity i2 = -1 to compute the powers of i and complete the table.
X=200 2/3 of 15 is 10 make that negative add it to the other side 1/5x = 40 and then multiply 40 by 5 to get your answer Check 1/5 of 200 is 40 - 10 = 30 40-10=30 30=30
