YOUR ANSWER 10 = 1 x 2 x 5
10 = 1 x 2 x 5Positive divisor of 10 are 1, 2 and 5.
10 = 1 x 2 x 5Positive divisor of 10 are 1, 2 and 5.∴ A = {1, 2, 5}.
10 = 1 x 2 x 5Positive divisor of 10 are 1, 2 and 5.∴ A = {1, 2, 5}.2, 3, 5 and 7 are prime numbers less than 10.
10 = 1 x 2 x 5Positive divisor of 10 are 1, 2 and 5.∴ A = {1, 2, 5}.2, 3, 5 and 7 are prime numbers less than 10.∴ B = {2, 3, 5, 7}.
10 = 1 x 2 x 5Positive divisor of 10 are 1, 2 and 5.∴ A = {1, 2, 5}.2, 3, 5 and 7 are prime numbers less than 10.∴ B = {2, 3, 5, 7}.Let x be constant function from set A to set B.
10 = 1 x 2 x 5Positive divisor of 10 are 1, 2 and 5.∴ A = {1, 2, 5}.2, 3, 5 and 7 are prime numbers less than 10.∴ B = {2, 3, 5, 7}.Let x be constant function from set A to set B.i.e. x(a) = b, where a ∈ A and b ∈ B and b is a fixed constant.
10 = 1 x 2 x 5Positive divisor of 10 are 1, 2 and 5.∴ A = {1, 2, 5}.2, 3, 5 and 7 are prime numbers less than 10.∴ B = {2, 3, 5, 7}.Let x be constant function from set A to set B.i.e. x(a) = b, where a ∈ A and b ∈ B and b is a fixed constant.Then numbers of constant functions = n(B) = 4.
