Answer 1

Your Question:

if A ={x belongs to C : x^2=1} and B={x belongs to C: x^4=1} then write A-B and B-A

Step-by-step explanation:

We have:

A=( x ∈ C: x² = 1)

⇒A=( -1, 1)

And,

B=( x ∈ C: x^4 =1)

⇒= ( x^4 -1 =0

B= {( x²- 1) ( x² + 1)}

⇒B = (-1, 1, -i, i)

Thus, we get:

A - B =∅

And,

B - A= { -i, i}
