Question

Which of these numbers are not like the others? 25,16,49,63,81

Answer 1

63. It is not a perfect square like the others.

or

16. It is the only even number

I would take into consideration what you have been learning to make the choice of which one would better fit the assignment. ( I would think that it would be 63, but it could be either.)

Answer 2

63 is not like the others

All the other numbers are perfect squares:

5*5 = 5² = 25

4*4 = 4² = 16

7*7 = 7² = 49

9*9 = 9² = 81

There is no number that when squared will give you 63

Hope this helped!
