No it is not. 22 is not a perfect square because it is not a product of a rational number multiplied by itself. The closest perfect square would be 25

no it is not beacuse if u add all its factor which r 1,2,19 u get 22 and a perfect number has to be wgen u add up all the factors u get the number itself...
400 can be factored as 24 * 52, or 22 * 22 * 52. A perfect square factor of 400 will always have an even exponent, so here is a list: 12, 22, 42, 52, 102, and 202.
64. 64 = 82 = 43 26 = (23)2 = (22)3 = 64.
It isn't a perfect number.A perfect number is a number which is the sum of its proper divisors (including 1, but excluding itself).The divisors of 20 are 1, 2, 4, 5, 10.1 + 2 + 4 + 5 + 10 = 22 => 20 is not a perfect number.An example of a perfect number is 28:The divisors of 28 are 1, 2, 4, 7, 141 + 2 + 4 + 7 + 14 = 28 => 28 is a perfect number.
"Perfect square" refers to the square of a whole number, starting with: 02 = 0 12 = 1 22 = 4 32 = 9 etc.
