1. there are 7 seventh roots of 1. find three of the non-obvious ones find the angles a in radians. do not write a = 0, 360 degrees or any coterminal angle to o those are obvious ) two roots are z = cos a + i sin a where a= or a= or a= can someone me for this question i kinda confused pls explain to me step by step?

The 7th roots of 1 are the numbers such that . They take the form

with ranging from 0 to 6. This is because, when you raise any of these to the 7th power, by DeMoivre's theorem we get

Then the roots themselves are

10 glasses of juice could be made with 5 carrots, 1,500 orange juice, 2,000 papaya juice.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
