1+13^4+13^8+...+13^96+13^100/1+13^2+13^4+...+13^98+13^100+13^102
Tinh tong:
13/3+13/6+13/10+13/15+13/21+13/28+13/36+13/45+13/55
chứng minh 13 x 7 = 28
chứng minh 28 : 7 = 13
chứng minh 13+13+13+13+13+13+13=28
C=(13^12+13^14^+13^16)÷(13^10+13^12+13^14)
13 x 13 x 13 x 13 x 13 x 13 = x.......
\(A=\frac{1+13^4+13^8+..+13^{96}+13^{100}}{1+13^2+13^4+..+13^{98}+13^{102}}\)TÍNH A
cho A = 13+13^2+13^3+13^4+...............+13^99+13^100 . Chứng minh rằng A chia hết cho 182
So sánh 10^2000+5/10^2001-8 và 10^2000+6/10^2001-7
Tính 1+13^4+13^8+...+13^96+13^100/1+13^2+13^4+...+13^98+13^100+13^102
Tính A=2/5.7+5/7.12+9/19.28+11/28.39+1/39.40
Tính: (1312+1314+1316):(1310+1312+1314)
Tính giúp mình với !!!!!
1/13 . 8/13- 14/13 + 5/13 . 1/13
