So1912+2m.

( 1)

Because 2 10 = 1024.

2^ 1 1=2048

Therefore, from the left side of the inequality (1), n >；; 10

Because m

That is 2 n-2 (n- 1) < =20 10.

Sulfur dioxide (n- 1) < =20 10

So n- 1

So n= 1 1.

So1912+2m.

That is 38 people

So m=6 or 7.

So the elements of M-intersection P are 2 1 1-2 6 and 2 1 1-2 7.

So the element sum is 3904.
