Answer 2

Answer:

2,3,7 and 8

Step-by-step explanation:

0, 1, 4, 9, 16, 25, 36, 49, 64, 81

These are the squares of numbers from 0 to 9... every number will end with one of these 10 digits and we know by multiplication that the last digit of the answer is given by the product of the last digit of the multiplicand with the last digit of the multiplier and in this case, the last digits will always be the same number... Hence, we can conclude that no perfect square can end with 2, 3, 7 or 8 since they are never the last digits of any square of any number from 0 to 9.
