Compare sizes 2008 2007 and 2007 2008 to process .

If it is a high school question, you can use logarithmic calculation to compare:

Let x=2008 2007, y=2007 2008, then lgx=lg(2008 2007)=2007·lg2008, check the commonly used logarithmic table to get lg2008=, so lgx=2007, and then check the antilogarithm table to get x = followed by 6625 consecutive 0s, which is a 6629 digit).

lgy = lg (2007 2008) = 2008 · lg2007, check the commonly used logarithmic table to get lg2007=, so lgy = 2008, and then check the anti table to get y = followed by 6629 consecutive zeros, is 6632 digits).

So, 2008 2007 is less than 2007 2008.

If you haven't learned logarithms, you have to use observational analogy to compare:

It can be seen that when a b (a and b are both non-zero natural numbers), a b and b a are compared with 2 1 1 and 3 2, from 4 and 3 4 onwards, they are all in accordance with a b b a, so 2008 2007 2007 2008.

2007 2008=1-1 Zheng Zeji 2008

So 2006 Silver Song 2007

2006 2005 is greater than 2008 2007

Because it is possible to think at the limit, because 2005 2006 is closer to 1 1 than 2007 2008, so, it is still the latter larger.

Or compare with a reciprocal:

2006 2005 = 1 and 1 2005

2008 2007 = 1 and 1 2007

1 and 1 2005> 1 and 1 2007 reversed:

2006 2005 is greater than 2008 2007

Because you can use the limit of patience thinking, because 2005 2006 is closer to 1 1 than 2007 2008, so it is still the latter to defend the future.

Or compare with a reciprocal:

2006 2005 = 1 and 1 which noisy 2005

2008 2007 = 1 and 1 2007

1 and 1 2005> 1 and 1 2007 reversed:

Subtract three fractions from 1 to get 1 2008, 1 2009, 1 2010, and then compare the magnitude of these three fractions, 1 2008> 1 2009> 1 2010, and get 2007 2008< 2008 2009< 2009 2010

The two fractions are divided, and the round grinds to see how they are worth the result in relation to 1.

Tong Zhaodou 2008*2008).

So. 2007 2008 is less than chain shroud 2008 2009

Comparing (1 2008) with (1 2009) bending Li Wang burying the boy, it is clear that 1 2008 is a big disturbance, so (2007 2008) is less than (2008 2009).
