Question

(1/z)2 = 16

Answer 1

help me solve for z

Answer 2

z is from C or R?

Answer 3

so we can take squareroot of both sides so we will get 1/z = 4

therefore 1 = 4z --> 1/4 = z

Answer 4

1/z=-4 too

Answer 5

yup thanks for pointing that out. i still forget that.

since you are working with a squareroot you hvae to take both positive and negative answer. because (-4)^2 = 16 and so does (4)^2 = 16. so you hvae to take both positive nad negative answer into account
