Question

Suppose U= (2,4,6,8,10) is the universal set and B= (1,4,9). What is B? Please Explain! Help!

Answer 1

So U is the set of `even numbers less than or equal to 10`.
Or at least that's the way it looks.

Let's write our set B like this:\[\Large\bf\sf B\quad=\quad \{1^2,\;2^2,\;3^2\}\]

Answer 2

Because it looks like B is the set of squared values in the same range as U.

Answer 3

Something like that maybe :\
