Answer:
\(\left(1+\frac{8}{10}\right).\left(1+\frac{8}{22}\right).\left(1+\frac{8}{36}\right)...\left(1+\frac{8}{8352}\right)\)
\(=\frac{18}{10}.\frac{30}{22}.\frac{44}{36}...\frac{8360}{8352}\)
\(=\frac{2.9.3.10.4.11....88.95}{1.10.2.11.3.12...87.96}\)
\(=\frac{\left(2.3.4...8\right).\left(9.10.11...95\right)}{\left(1.2.3...87\right).\left(10.11...96\right)}\)
\(=\frac{9.88}{96}\)
\(=\frac{3}{4}\)
Tính: \(S=\left(1+\frac{8}{10}\right)\left(1+\frac{8}{22}\right)\left(1+\frac{8}{36}\right)...\left(1+\frac{8}{8352}\right)\))
Tính nhanh:
G=\(\left(1+\frac{8}{10}\right)\left(1+\frac{8}{22}\right)\left(1+\frac{8}{36}\right).....\left(1+\frac{8}{8352}\right)\)
Tính A=\(\left(1+\frac{8}{10}\right)\left(1+\frac{8}{22}\right)\left(1+\frac{8}{36}\right)...\left(1+\frac{8}{8352}\right)\)
Tính
\(\left(1+\frac{8}{10}\right).\left(1+\frac{8}{22}\right).\left(1+\frac{8}{36}\right)....\left(1+\frac{8}{8352}\right)\)
Tính (1+8/10).(1+8/11).(1+8/36).....(1+8/8352)
tính
a,(1+8/10).(1+8/22).(1+8/36).(1+8/52)................(1+8/8352)
b,2.4+3.5+4.6+5.7+6.8+...............+97.99+98.100
tìm GTNN của A= |x^2+5| +(2y-3)\(^4\)
\(A=1+2+2^2-2^3+2^4-2^5+...+2^{2016}\)
\(B=\left(1+\frac{8}{10}\right).\left(1+\frac{8}{22}\right).\left(1+\frac{8}{36}\right)...\left(1+\frac{8}{8352}\right)\)
Tính A = (\(\frac{8}{10}+1\)) . (\(\frac{8}{22}+1\)) . (\(\frac{8}{36}+1\)) .... (\(\frac{8}{1900}+1\))
So sánh A và B :
a,A=20/39+22/27+18/43,B=14/39+22/29+18/41
b,A=3/8^3+7/8^4,B=7/8^3+3/8^4
c,A=10^7+5/10^7-8,B=10^8+6/10-7
d,A=10^1992+1/10^1991+1,B=10^1993+1/10^1992+1
