Question

write the following set in builder form A={16,25,36,49,64,81},B={3,6,9,12,15,18}​

Answer 1

Answer:

A={ x: x=n^2, 3<n<10, n belongs to Natural number}

B={ x: x= 3n, 0<n<7, n belongs to Natural number}

Step-by-step explanation:

let A= {16,25,36,49,64,81}

this can be written as: A= {4^2, 5^2, 6^2, 7^2, 8^2, 9^2}

A={ x: x=n^2, 3<n<10, n belongs to Natural number}

B={ 3,6,9,12,15,1}

this can be written as: B={ 3x1,3x2,3x3,3x4,3x5,3x6}

B={ x: x=3n, 0<n<7, n belongs to Natural number}
