11/14 i^(5)

Question

I need help with this question

Answer 1

I assume you mean (11/14)(i⁵).

i=√-1

i²=-1

i³=-√-1

i⁴=1

i⁵=√-1

i⁶=-1

i⁷=-√-1

i⁸=1

do you see the pattern ?  it repeats itself over and over

(11/14)(i⁵)

(11/14)(i⁴)(i)

(11/14)(1)(i)

(11/14)i or you could simply say...

(11/14)(√-1) where √-1=i, so...

(11/14)i is the answer
