chứng minh rằng:
S=(1/3)-(2/32) + (3/33) - (3/34) +.....+(99/3990)-(100/3100)<3/16Chứng minh rằng : 1/3-2/3^2+3/3^3-4/3^4+...+99/3^99-100/3^100<3/16
- Chứng minh rằng :
1/3 - 2/3^2 + 3/3^3 - 4/3^4 + ... + 99/3^99 - 100/3^100 < 3/16
CHỨNG minh rằng:1/3-2/3mũ 2+3/3mũ 3-4/3 mũ 4+...+99/3 mũ 99-100/3 mũ 100<3/16
Chứng minh rằng: A=\(\dfrac{1}{3}-\dfrac{2}{3^2}+\dfrac{3}{3^3}-\dfrac{4}{3^4}+...+\dfrac{99}{3^{99}}-\dfrac{100}{3^{100}}< \dfrac{3}{16}\)
Chứng minh rằng:
1/3 - 2/3^2 + 3/3^3 - 4/3^4+......+ 99/3^99 - 100/3^100 < 3/16
Các bạn giúp mình với, mình cảm ơn
