Bài 1 : cho 2 biểu thức
\(A=\left(1-\frac{1}{2}\right)\left(1-\frac{1}{3}\right)...\left(1-\frac{1}{19}\right)\left(1-\frac{1}{20}\right)\)
\(B=\left(1-\frac{1}{4}\right)\left(1-\frac{1}{9}\right)\left(1-\frac{1}{16}\right)...\left(1-\frac{1}{81}\right)\left(1-\frac{1}{100}\right)\)
So sánh A với \(\frac{1}{21}\)
So sánh B với \(\frac{11}{21}\)
So sánh
\(\left(\frac{1}{16}\right)^{10}va\left(\frac{1}{2}\right)^{50}\)
