Question

if A ={1,4,9,16,25,36,49,64,81,100} B={all even numbers less than 10} (i)AUB (ii)AnB (iii) A-B (IV) B-A​

Answer 1

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

B = { 2, 4, 6, 8 }

i)

A U B = { 1, 2, 4, 6, 8, 9, 16, 25, 36, 49, 64, 81, 100 }

ii)

A n B = { 4 }

iii)

A - B = { 1, 9, 16, 25, 36, 49, 64, 81, 100 }

iv)

B - A = { 2, 6, 8 }
