Show that the following numbers are not perfect squares:
(i) 9327
(ii) 4058
(iii) 22453
(iv) 743522.

To do:

We have to show that the given numbers are not perfect squares.

Solution:

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

(i) Here, the unit digit of the given number is 7.

Therefore,

9327 is not a perfect square.   

(ii) Here, the unit digit of the given number is 8.

Therefore,

4058 is not a perfect square.   

(iii) Here, the unit digit of the given number is 3.

Therefore,

22453 is not a perfect square.   

(iv) Here, the unit digit of the given number is 2.

Therefore,
