Which of the following will have 4 at the unit's place?
a. 14²
b. 62²
c. 27²
d. 35²

Solution:

We have to find the square of the number which will have 4 at the unit’s place.

The unit digit of a perfect square can be only 0, 1, 4, 5, 6 or 9.

The unit’s place of 14² = 4² = 16 = 6

The unit’s place of 62² = 2² = 4

The unit’s place of 27² = 7² = 49 = 9

The unit’s place of 35² = 5² = 25 = 5

Therefore, 62² will have 4 at the unit’s place.
