Question

(5) If A={-3, -2, 1, 43 and B= {0, 1, 2, 4y find(i) A-B
(1) B-A​

Answer 1

Answer:

(1).3,3,(-1),4y-43

(i).(-3),(-3),1,43-4y

Step-by-step explanation:

Value of A is = -3,-2,1,43

Value of B is = 0,1,2,4y

Now, acco. to ques.

1.B-A

By putting each value of A and B one time in question

At first B=0,A=-3

B-A={0-(-3)}

B-A={0+3}

B-A=3

Now B=1,A=-2

B-A={1-(-2)}

B-A={1+2}

B-A=3

Now B=2,A=1

B-A=2-1

B-A=1

Now B=4y,A=43

B-A=4y-43

Now,

(i).A-B

By putting each value of A and B one time in question

By putting each value of A and B one time in questionAt first A=-3,B=0

A-B={(-3)-0}

A-B={-3}

Now A=-2,B=1

A-B={(-2)-1}

A-B={-3}

Now A=1,B=2

A-B=1-2

A-B=(-1)

Now A=43,B=4y

A-B=43-4y
