​

Answer 1

Answer:

16

Step-by-step explanation:

no.subsets of a given set with 'n' no. of elements = 2^n

here, no. of elements, n = 4

therefore, no. of subsets = 2^4 = 16

{ }, {1}, {4}, {9}, {16}, {1,4}, {1,9}, {1,16}, {4,9}, {4,16}, {9,16}, {1,4,9}, {4,9,16}, {9,16,1}, {16,1,9}, {1,4,9,16}
