How many two-digit numbers satisfy this property?
The last digit (unit's digit) of the square of the two-digit number is 8.
Show answer & explanation
Correct answer: D
Explanation
The last digit of the square of any integer can only be 0, 1, 4, 5, 6, or 9.
The last digit of a square can never be 8.
Therefore, there is no two-digit number whose square ends in 8.
