So Sánh A và B biết:
A = \(\frac{5^{2016}+1}{5^{2017}+1}\)và B = \(\frac{5^{2017}+1}{5^{2018}+1}\)
So sánh A và B, biết:
A =\(\frac{10^{2016}+1}{10^{2017}+1}\)và B =\(\frac{10^{2017}+1}{10^{2018}+1}\)
SO SÁNH A và B : A=2016/(1*2)+2016/(3*4)+2016/(5*6)+......+2016/(1999*2000) và B=2017/1001+2017/1002+2017/1003+......+2017/2000
So sánh \(A=\frac{2^{2018}-3}{2^{2017}-1}\) và \(B=\frac{2^{2017}-3}{2^{2016}-1}\)
so sánh 2 số A và B nếu
\(A=-\frac{1}{2018}-\frac{3}{2017^2}-\frac{5}{2017^3}-\frac{7}{2017^4};B=\frac{-1}{2018}-\frac{7}{2017^2}-\frac{5}{2017^3}-\frac{3}{2017^4}\)
A = \(\frac{\frac{3}{4}-\frac{3}{11}+\frac{3}{13}}{\frac{5}{4}-\frac{5}{11}+\frac{5}{13}}+\frac{\frac{1}{2}-\frac{1}{3}+\frac{1}{4}}{\frac{5}{4}-\frac{5}{6}+\frac{5}{8}}\)
B = \(\frac{2^{12}.3^5-4^6.9^2}{\left(2^2.3\right)^6+8^4.3^5}-\frac{5^{10}.7^3-25^5.49}{\left(125.7\right)^3+5^9.14^3}\)
C = \(\frac{\left(a^{2016}+b^{2016}\right)^{2017}}{\left(c^{2016}+d^{2016}\right)^{2017}}\)= \(\frac{\left(a^{2017}-b^{2017}\right)^{2016}}{\left(c^{2017}-d^{2017}\right)^{2016}}\)
so sánh
a) \(\frac{2016}{2017}\)và\(\frac{2017}{2018}\)
b)\(\frac{2017}{2016}\)và\(\frac{2018}{2017}\)
So sánh A và B nếu
\(A=\frac{-1}{2018}-\frac{3}{2017^2}-\frac{5}{2017^3}-\frac{7}{2017^4}\)
\(B=\frac{-1}{2018}-\frac{7}{2017^2}-\frac{5}{2017^3}-\frac{3}{2017^4}\)
So sánh :
\(A=\frac{2^{2018}-3}{2^{2017}-1};B=\frac{2^{2017}-3}{2^{2016}-1}\)
