yy 花式字幕剧情介绍:
In this case, we begin by noting that ifwe take four different numbers no more than afixed integer mand form the sum of their cubes, the result is less than 4m3. However, ifm=1000, then an elementary calculation shows that the number of sums of four different cubes is more than 10 times the number 4m3, from which it follows that some number n≤4m3=4,000,000,000 must be the sum of four cubes in at least ten different ways. The details involve calculations using binomial coefficients(introduced in Chapter 5)and are not especially difficult.
