The question says m is a set of all square numbers less than 80 and n is a set of all non -n negative even numbers that are under 30.
00:09
What do m and n have in common? so first one we'll tell all the values of m.
00:14
So now m is all the square numbers less than 80, so i would say m is 1, that's 1 squared, 2 squared is 4, 3 squared is 9, 4 squared is 16, 5 squared is 25, 6 squared is 36, 7 squared is 49, and 8 squared is 64, 3 3, 312.
00:30
Then 9 squared to be 81, but we're going to be under 80.
00:33
So that wouldn't work.
00:35
Now i need to worry about the members of n, which are all non -native even numbers are under 30.
00:40
So n would be 2, 4, 6, 8, 10, 12, 14, 16, 18, 22, 24, 26, 28.
00:48
And 30 is the next even number, but we're going to be under 30.
00:51
So that would be the last one.
00:53
Now we want to figure out which ones they have in common...
