Question

. B is the set of all x such that x squared is equal to 9

Answer 1

Answer:

B={ y:y is set of all x}

set=2m

m=1

2¹=2

B={{},x}

x²=9 so

x=√9

x=3

B={{},3}

Answer 2

The answer is B = { 3, -3}

Given:  B is the set of all x such that x squared is equal to 9

To find: set of B

Solution: Given B is a set of numbers such that x² = 9

take the value which satisfy x² = 9 condition

⇒ x = 3  then  3² = 9

⇒ x = -3 then  (-3)² = 9

therefore, the set B = { 3, -3}
