Question

In each of the following, state whether A=B or not.


(1)A={a,b,c,d} B={d,c,a,b}
(2)A = {4, 8, 12,16} B={8,4,16,18}
(3)A = {2, 4, 6, 8, 10} B= {x:x is a positive even integer and x < 10}
(4)A= {x: x is a multiple of 10} B = {10, 15, 20, 25, 30, ...}​

Answer 1

Answer:

1 and 2 a=b

Step-by-step explanation:

in 3 and 4it is not because in a all positive even integers and x is strictly less than aur equal to 10. so so 3rd one doesn't apply the formula a is equal to b. and in the fourth case 15 and 225 are not the multiples of 10 therefore a is not equal to b.

please mark the answer is the brainiest. hope it helps.
