9 16 25 43​


Sagot :

Answer:

43

Step-by-step explanation:

not a perfect square

Answer: 9

Step-by-step explanation: 9 doesn't belong, because if you add up the digits in all of the other numbers, they give you 7. 9 is the only number that doesn't give you 7. I say 16 is the number that doesn't belong because 9, 25, and 43 are all odd numbers and 16 is even.
