So here are my questions. I chose the questions:
11.What is the square of each number?
Answer: The answer is 81 because 9x9=81.
Answer: The answer is 121 because 11x11=121
My second question is:
17. A fridge magnet has an area of 54 mm2. Is 54 a perfect square? Use prime factorization to find the answer.
Answer: The answer is 2x3x3x3. And 54 is not a perfect square because it has an odd number of factors of 2 and 3.
Please comment and tell me if I did anything wrong so I can fix it.
