Answer:
the first one
Step-by-step explanation:
in the first one it says there are no common numbers between x and y which is false.
in the second one its the union of x and y which means that you must list all numbers in x and y without repetition
the third one states that 15,33,1025 are the only numbers that are common between x and y.
so as a breif the first one is wrong
21 V³ 15- 9V³15
= (21-9)V³15
= 12V³15
(x,y) =(7/2,4)
I hope this helps you
