A=(2009/2010).(2008/2010). ... . (-2010/2010)
Còn lại mình chịu
\(A=\left(1-\frac{1}{2010}\right).\left(1-\frac{2}{2010}\right).\left(1-\frac{3}{2010}\right)....\left(1-\frac{2011}{2010}\right)\)
Tính:
\(A=\left(1-\frac{1}{2010}\right)\left(1-\frac{2}{2010}\right)\left(1-\frac{3}{2010}\right)...\left(1-\frac{4020}{2010}\right)\)
\(B=3+7+13+21+31+43+57+...+9901\)
\(C=\left(1-\frac{4}{1^2}\right)\left(1-\frac{4}{3^2}\right)\left(1-\frac{4}{5^2}\right)...\left(1-\frac{4}{2015^2}\right)\)
\(D=1-\frac{1}{1+2}-\frac{1}{1+2+3}-\frac{1}{1+2+3+4}-...-\frac{1}{1+2+3+4+...+100}\)
\(E=1+2+3+4+5+6+...+1000000\)
Giải giúp tớ với nhé! Ai giải đúng mình sẽ tick cho 3 cái.
Tính tich : \(A=\left(1-\frac{1}{2010}\right).\left(1-\frac{2}{2010}\right).\left(1-\frac{3}{2010}\right)......\left(1-\frac{2011}{2010}\right)\)
Tính A= \(\left(1-\frac{1}{2010}\right).\left(1-\frac{2}{2010}\right).\left(1-\frac{3}{2010}\right)....\left(1-\frac{2011}{2010}\right)\)
Tính tích:
A = \(\left(1-\frac{1}{2010}\right)\left(1-\frac{2}{2010}\right)\left(1-\frac{3}{2010}\right)...\left(1-\frac{11}{2010}\right)\)
Giúp với!Còn quà thì tính sau nhé!

GIÚP MK VỚI MK ĐANG CẦN GẤP
Tính \(\left(1-\frac{1}{2010}\right)\left(1-\frac{2}{2010}\right)...\left(1-\frac{2016}{2010}\right)\)
Tính giá trị biểu thức
a, \(A=2010^{2010}.\left(7^{10}:7^8-3.16-2^{2010}:2^{2010}\right)\)
b, \(B=\left(\frac{1}{7}+\frac{1}{23}-\frac{1}{1009}\right):\left(\frac{1}{23}+\frac{1}{7}-\frac{1}{1009}+\frac{1}{7}.\frac{1}{23}.\frac{1}{1009}\right)+1:\left(30.1009-160\right)\)
\(\frac{1}{2011}.x=\left(1-\frac{1}{2}\right).\left(1-\frac{1}{3}\right).\left(1-\frac{1}{4}\right)....\left(1-\frac{1}{2010}\right).\left(1-\frac{1}{2011}\right)\)
