Question

4, 9, 256, 529, 573 which of these does not belong to the group.

Answer 1

573 is the answer as 573 does not belong to group

$4 = {2}^{2}$

$9 = {3}^{2}$

$256 = {16 }^{2}$

$529 = {23}^{2}$

573 is not a whole square

while all other terms are whole square

so 573 does not belong to group
