Answer
1
Find the multiples of 10 to get the elements of set A.
A = {10, 20, 30,...}
2
Determine whether both sets have exactly the same elements.
Answer: No. A $≠$ B
Reason: Set B contains elements like 15 and 25, which are not multiples of 10. Therefore, the two sets do not contain exactly the same elements, so A $≠$ B
