Q. Chen starts with a number.\newlineHe squares his number.\newlineHis answer is 144144\newlineWrite down the two possible values of the number Chen starts with.
  1. Find Square Root: Chen's number squared is 144144, so we need to find the square root of 144144 to find Chen's number.\newline144\sqrt{144}
  2. Consider Positive and Negative: The square root of 144144 is 1212, but since squaring a negative number also gives a positive result, the number could also be −12-12.\ So, Chen's number could be 1212 or −12-12.
