Let `A={x : x in N},\ B={x ; x2n ,\ n in N},\ C={x : x=2n-1, n in N}a n d ,\ D={x : x` is a prime natural number`}` . Find: `BnnD`

Explanation

We have given `A={x : x in N},\ B={x ; x2n ,\ n in N},\ C={x : x=2n-1, n in N}a n d ,\ D={x : x`
is a prime natural number}

Now we can write `A={x : x in N}``={1,2,3,4.....}`

Similarly, `\ B={x ; x2n ,\ n in N}={2,4,6,8,10....}`,

`\ C={x : x=2n-1, n in N}={1,3,5,7,9.......}`
a n d

`\ D={x : x`
is a prime natural number}`={2,3,5,7,11,13....}`
