Cảm ơn nhé! Nhớ giải hẳn ra hộ mình nhé!
Chứng minh S=1/1+1/16+1/36+1/64+1/100+1/144+1/196<1/2
Cho
A= 1/4+1/16+1/36+1/64+1/100+1/144+1/196+1/256+1/324+1/400. Chứng minh A < 1/20
chứng minh rằng
\(\frac{1}{4}+\frac{1}{16}+\frac{1}{36}+\frac{1}{64}+\frac{1}{100}+\frac{1}{144}+\frac{1}{196}<\frac{1}{2}\)
