The following numbers are obviously not perfect square give reason 3 6667

Answer»

ANSWER:

because to fulfill the requirements to be a perfect square a no. should be expressed as the PRODUCT of two equal (same) integers. eg: 36 // (6*6)

but,

66 we cannot GET by multiplying any same .we can get by :

33*2=66

11*6=66

1*66=66

but in any of above both the elements of L. H. S are not same as in the case above (36,25,81,,etc).
