Question

Give reasons why the given number are not perfect squares.12000,1227,790​

Answer 1

Answer:

in the first case :12000

since this number has 3 zeros( recall back that any number which has odd number of zeros after it are not perfect square and 3 is an odd number)

in the second case:1227

in this,the unit digit is 7(as we know that any number whose unit digit is 2,3,7 or 8 are not perfect squares, you can get the reason if you observe the squares from 1 to 10)

in the third case:790

the number ends with a single zero (and I've already stated it in the first case)
