Step-by-step explanation:
(i) T = { 4, 8, 12}
U = {1,2,3,4,6,8,12,24}
(iii) TUU = {1,2,3,4,6,8,12,24}
(iv) yes, because all the elements in T are also the elements in U.
I believe the answer would be 0 because -0 isn’t really a think so 0 would be the only solution
3.06; lining it up 4*9= 36, write the 6 and carry the 3, then 9*3= 27, add 3 and you get 30. Since in your original problem you have two places behind the decimal point you do the same with your answer so that 306 turns into 3.06
