Set g is the set of positive integers divisible by 4 in set if is the set of perfect squares list the first five elements of set age which contains numbers and g that are also elements of f

The set G is:

G={4, 8, 12, 16, 20, 24, 28, 32, 36, ...}

The set F is the set of perfect squares:

F={1, 4, 9, 16, 25, 36, 49, 64, 81, 100 ...}

in set F,  4, 16, 36, 64 and 100 are multiples of 4.

{4, 16, 36, 64, 100}

The answer is 10 bud
