Ex 6.1 Class 8 Maths Question 2. The following numbers are not perfect squares. Give reason. (i) 1057 (ii) 23453 (iii) 7928 (iv) 222222 (v) 64000 (vi) 89722 (vii) 222000 (viii) 505050

(i) 1057 ends with 7 at unit place. So it is not a perfect square number. (ii) 23453 ends with 3 at unit place. So it is not a perfect square number. (iii) 7928 ends with 8 at unit place. So it is not a perfect square number. (iv) 222222 ends with 2 at unit place. So it is not a perfect square number. (v) 64000 ends with 3 zeros. So it cannot a perfect square number. (vi) 89722 ends with 2 at unit place. So it is not a perfect square number. (vii) 22000 ends with 3 zeros. So it can not be a perfect square number. (viii) 505050 ends with 1 zero. So it is not a perfect square number.
