Question

(2/3j)to the power of 2

Answer 1

just multiply 2/3 by 2/3rds

Answer 2

then put the j after the answer

Answer 3

= (2/3j) x (2/3j)
= (2 x 2) / (3j x 3j)
Not sure if j is a complex number, if its not then
= 4/9j^2
If it is complex
then
= -4/9

Answer 4

\[(\frac{ 2 }{ 3j })^2=\frac{ 2^2 }{ (3j)^2 }=\frac{ 4 }{9j^2}\]

Answer 5

@sd2452 Are you sure there is a J there?

Answer 6

so the answer is: 4/9j

Answer 7

j^2..
