Đề phải là so sánh chứ bạn !
Có : 2006A = 2006^2006+2006/2006^2006+1 = 1 + 2005/2006^2006+1
2006B = 2006^2007+2006/2006^2007+1 = 1 + 2005/2006^2007+1
Vì : 2006^2006 < 2006^2007 => 2006^2006+1 < 2006^2007+1
=> 2005/2006^2006+1 > 2005/2006^2007+1
=> 2016A > 2016B
=> A > B
Tk mk nha
Tính một cách hợp lí giá trị của các biểu thức sau:
A=3+6+9+12+...+2007
B=2.53.12+4.6.87-3.8.40
C=(\(\frac{\frac{2006}{2}+\frac{2006}{3}+\frac{2006}{4}+...+\frac{2006}{2007}}{\frac{2006}{1}+\frac{2006}{2}+\frac{2006}{3}+...+\frac{1}{2006}}\)
So sánh:A=\(\frac{2006^{2006}+1}{2007^{2007}+1}\)và B=\(\frac{2006^{2005}+1}{2006^{2006}+1}\)
Tinh A = \(\frac{\frac{2006}{1}+\frac{2006}{2}+\frac{2006}{3}+........\frac{2006}{2006}+\frac{2006}{2007}}{\frac{1}{2006}+\frac{2}{2005}+\frac{3}{2004}+.........+\frac{2005}{2}+\frac{2006}{1}}\)
so sánh A=\(\frac{2006^{20006}+1}{2007^{2007}+1}\)và B=\(\frac{2006^{2005}+1}{2006^{2006}+1}\)
so sánh \(\frac{2006^{2006+1}}{2006^{2007}+1}\)và \(\frac{2006^{2005+1}}{2006^{2006+1}}\)
So sánh:A=\(\frac{2006^{2006}+1}{2007^{2007}+1}\)và B=\(\frac{2006^{2005}+1}{2006^{2006}+1}\)
Các bạn trình bày giùm mình luôn nhé!!!!
tính hợp lí C=\(\frac{\frac{2006}{2}+\frac{2006}{3}+\frac{2006}{4}+...+\frac{2006}{2007}}{\frac{2006}{1}+\frac{2005}{2}+\frac{2004}{3}+...+\frac{1}{2006}}\)
\(\frac{\frac{2006}{2}+\frac{2006}{3}+\frac{2006}{4}+...........+\frac{2006}{2007}}{\frac{2006}{1}+\frac{2005}{2}+\frac{2004}{3}+.............+\frac{1}{2006}}\)
Tinh A = \(\frac{\frac{2006}{1}+\frac{2006}{2}+.......+\frac{2006}{2007}}{\frac{2006}{1}+\frac{2005}{2}+\frac{2004}{3}+.......\frac{1}{2006}}\)
