=77× 13+255×999+255×2

=77× 13+255×(999+2)

=77× 13+255× 100 1

= 1 1×7× 13+255× 100 1

= 1 1×9 1+255× 100 1

= 100 1+255× 100 1

= 100 1×(255+ 1)

= 100 1×256

=256256

1995=5*3*7* 19

Then any divisor of 1995 can be expressed as: (a of 5) * (b of 3) * (a of 7) * (d of19).

The values of a, b, c and d are all 0 or 1, so there are 2 * 2 * 2 = 16 approximations.

They are:

1,5,3,7, 19, 15,35,95,2 1,57, 133, 105,285,665,399, 1995

8.8 = 10- 1.28.98 = 10- 1.028.998 = 10- 1.0028.9998 = 10-65438+

Xue Xue and Hao Hao must both be multiples of 1 1, so their product must be multiples of 12 1 (= 1 1). 36438.86666666667

58 is "math",

So the answer is: 5.

Let the wide side AB of a rectangle be x meters and the long side BC be 2x meters.

(x+2x+x)=20× 1.2

4x=24

x=6

The long side BC is 6× 2 = 12m, and12 and 6 are exactly integer multiples of 1.2, so the maximum area enclosed by a rectangle is12× 6 = 72m2;

In other words, it is a rectangle surrounded by three sides, with long side 10 and wide side 5.

Because Xiao Hu and Xiao Tu didn't misread B, B is the common divisor of 1274 and 8 19.

1274=2×7×7× 13

8 19=3×3×7× 13

The common divisors of 1274 and 8 19 are 1, 7, 13 and 9 1 respectively. But 1 and 7 can be excluded from "B number is two digits"; 9 1 can be ruled out from "the number of nails misread by small painting is also two digits" (otherwise, the number of nails misread by small painting can only be one digit 9). Therefore, the number b must be 13.

According to the b number is 13, we can see that the a number of Xiao Hu Cuo is

1274÷ 13=98(8 is wrong)

What is Xiao Tu's wrong number?

8 19÷ 13=63(6 is wrong)

Therefore, the number a is 93.

The answer is 93.

(1) The scores of the four teams are 9, 7, 5, 3 or 7, 5, 3, 1. According to the meaning of the question, the score of each team can only be 7.

(2) Determine the score of team B, and you can know that team D has a score of 5;

(3) According to the rules of the game and consecutive odd scores, B is two wins and one draw, and D is two draws and one win. So two draws and two losses, A is two losses and one win, so the score of C is at least 1.

So the answer is: C.

Number six eight.
