Let `R={x|x inN,x" is a multiple of 3 and x"le100}`
`S={x|x in N, x" is a multiple of 5 and x "le100}`
What is the number of elements in `(RxxS)nn(SxxR)`?

Let R = {x|x in N , x is a multiple of 3 and xle100 } S= {x|x in N , x is a multiple of 5 and x le 100 }. What is the number of elements in: (Rxx S) nn (S xxR) ?

Let A={x;x in N,x is a multiple of 3} and B={x:x in N and x is a multiple of 5} . Write A nn B.

Let A={x ; x in N ,\ x is a multiple of 3 } and B={x : x in N\ a n d\ x is a multiple of 5 } . Write AnnB

If A = {x : x is a multiple of 3} and, B ={x : x is a multiple of 5}, then A-B is

if A ={x:x is a multiple of 3 } and , B={x:x is a multiple of 5 }, then A-B is

Let A = {x : x is a multiple of 3} and B = {x : x is a multiple of 5), then A nn B is given by

Let A = {x : x is a multiple of 3} and B = {x : x is a multiple of 5), then A nn B is given by

Let A = {x : x is a multiple of 3} and B = {x : x is a multiple of 5), then A nn B is given by

Let A = {x : x is a multiple of 3} and B = {x : x is a multiple of 5}, then A nn B is given by
