Give reason to show that none of the numbers given below is a perfect square:
(i) 5372
(ii) 5963
(iii) 8457
(iv) 9468
(v) 360
(vi) 64000
(viii) 2500000
By observing the properties of square numbers, we can determine whether a given number is a square or not.
(i) 5372
A number that ends with 2 is not a perfect square.
Thus, the given number is not a perfect square.
(ii) 5963
A number that ends with 3 is not a perfect square.
Thus, the given number is not a perfect square.
(iii) 8457
A number that ends with 7 is not a perfect square.
Thus, the given number is not a perfect square.
(iv) 9468
A number ending with 8 is not a perfect square.
Thus, the given number is not a perfect square.
(v) 360
Any number ending with an odd number of zeroes is not a perfect square.
Hence, the given number is not a perfect square.
(vi) 64000
Any number ending with an odd number of zeroes is not a perfect square.
Hence, the given number is not a perfect square.
(vii) 2500000
Any number ending with an odd number of zeroes is not a perfect square.
Hence, the given number is not a perfect square.
