Question

Express the radical using the imaginary unit, i.

Express your answer in simplified form.
±√-77= ±
2

Answer 1

Let î be the imaginary number

±√-77 = ±2

±√77î = ±2

î = ±2/±√77

î = ±2(±√77)/77

(don't forget the ± sign here)

Answer 2

Explanation:

Let î be the imaginary number

±√-77 = ±2

±√77î = ±2

î = ±2/±√77

î = ±2(±√77)/77

`i = (2√(77) )/(77)` (don't forget the ± sign here)
