Let z = e2π i /n. then zn = 1, and z is called an nth root of unity. there are n nth roots of unity, equispaced around the unit circle; they have the form z = e2π i (k/n), where k = 0, 1, 2, , n−1. of course 1 is an nth root of unity, for every n. draw the unit circle for the four 4th roots of unity. the angle difference (in radians) between adjacent 4th roots is correct: your answer is correct. draw the unit circle for the six 6th roots of unity. the angle difference (in radians) between adjacent 6th roots is correct: your answer is correct. draw the unit circle for the eight 8th roots of unity. the angle difference (in radians) between adjacent 8th roots

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

there is nothing below so i cannot
