Question

B=(x:x € N and x^2 is lessthan 4)​

Answer 1

Answer:

(x:x € N and x^2 is lessthan 4)

Answer 2

Answer:

{1}

Step-by-step explanation:

Natural numbers start from 1. So x must start from 1. Then, 2,3,4...

B = {x:x € N and x^2 is less than 4},

which means only those number can be in set which satisfy x^2 > 4.

Starting from 1:

1^2 = 1, which is less than 4. So we can have this in set B

Then, for 2:

2^2 = 4, note that 4 is equal to 4(not less).

So we wont count 2.

And now, all the numbers will have their square greater than 4.

So, B = {1}
