Cost method. 2009, 2010 = 15 * 80,000 = 120 (10,000 yuan) equity method. 2009 = 120 + 36 - 20 - 8 = 128 (10,000 yuan).

Solution: Original = (x +x-2y) (x+y) 1-x y 4)-x (1 y 4).

x²+x-2y²)/(x+y)² 1-x²y^4)-x²y^4）

x +x-2y ) (x+y) 1 Because x= 3+ 2 y= 3- 2 , so x-y=2 2 ,(x-y) =(2 2) =8

x² =(√3+√2)²=5+2√6

2y = 2( 3- 2) =10-4 6 = (5+2 6+ 3+ 2-10+4 6) 8 -1= ( 3+ 2-5+6 6) 8 -1 = ( 3+ 2-13+6 6) 8

1 square kilometer = 100 hectares = 1,000,000 square meters, square nursery 1 hectare = 10,000 square meters.

Rectangular nursery area = 500 80 = 40,000 square meters, 40,000 square meters 10,000 square meters.

The rectangular nursery has a large area.

Sum of the Difference Series: (First Term + Last Term) 2x Number of Terms = Sum.

Take the first question as an example: the first (first) term is 7, the last (last) term is 23, the number of terms (that is, how many numbers) is 9, 7+23) 2x9=135

This is a series of equal differences, the sum of the prime minister plus the last term multiplied by the number of terms divided by 2
