This question should be familiar with the formula of square difference, a2-b2=(a+b)(a-b).

Multiply (a-b) (a-b) on the far left of the whole equation, with a-b as the denominator, then the numerator becomes.

a-b）(a+b)(a2+b2)(a4+b4)(a8+b8)(a16+b16)(a32+b32)

a2-b2)(a2+b2)(a4+b4)(a8+b8)(a16+b16)(a32+b32)

a4-b4)(a4+b4)(a8+b8)(a16+b16)(a32+b32)

a8-b8)(a8+b8)(a16+b16)(a32+b32)=(a16-b16)(a16+b16)(a32+b32)=(a32-b32)(a32+b32)

a64-b64)

So the answer is b.

The first box input: (9+11) 5 The result is 4, the second box input: (15+1) 1, the result is 16, and the third box inputs: (11-1) 1, the result is 10, and the sum of the three is equal to 30.

First you can drink 10 2 5 bottles.

4 caps for one bottle, that is, +1 again, there is 1 cap left, 5 + 1 = 6 (6 bottles, 1 cap) now there are 6 bottles, you can exchange for 3 bottles 6 + 3 = 9 (3 bottles and 4 caps) 4 caps can be exchanged for 1 bottle.

9 + 1 = 10 (4 bottles and 1 cap) 4 empty bottles, you can change 2 bottles 10 + 2 = 12 (2 bottles and 3 caps) 2 empty bottles can be replaced with 1 more bottle 12 + 1 = 13 (1 bottle 4 caps) 4 caps can be exchanged for 1 bottle. 13 + 1 = 14 (2 bottles, 1 cap) 2, empty bottles can be replaced with 1 more bottle, 14 + 1 = 15 (1 bottle, 2 caps), if the boss allows, you can use one bottle instead of 2 caps, and then change one bottle, then you can drink 16 bottles, if the boss does not allow it, then you can only drink 15 bottles.

It's too simple, multiply twenty by a quarter and get the one that sells the next day. The second day sells plus twenty, multiply by half to get the third day sold, the first day plus the second day plus the third day plus five to get the batch of oranges.

solution, let the total weight be x, get.

x=20+x/4+1/2(20+x/4)+5x=20+x/4+10+x/8+5

5x/8=35

x=56（kg)

A, the total weight is 56 dry grams.

It's very simple, set x.

x-20-x/4-(20+x/4)*1/2 = 5

x = 56 kg.
