Suppose U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} is the universal set, and P = {1, 4, 9, }. What is p'?

{2,3,5,6,7,8}
{2,4,6,8}
{1,2,3,4,5,6,7,8,9,10}
{2,3,4,5,6,7,8,10}

suppose T={-8,-4,0,4,8,12,16,20} and K={-3,-2,-1,0,1,2,3,4,5,6}. What is T n K?

{-3,-2,-1,1,2,3,4,5,6}
{-8,-4,-3,-2,-1,0,1,2,3,4,5,6,8,12,16,20}
{-8,-4,8,12,16,20}
{0,4}****

Please help.

Thank you

  1. I see the elements 1,4, and 9 in P
    Which elements do you NOT see ?

    in your 2nd question, is that T and K, that is,
    the intersection of T and K ?
    if so, which elements can you find that are in both T and K ?
    If so, then you are correct.
