\(A=\frac{-7}{2016^{2015}}+\frac{-15}{2016^{2016}}=\frac{-7.2016}{2016^{2016}}+\frac{-15}{2016^{2016}}=\frac{-14127}{2016^{2016}}\)
\(B=\frac{-15}{2016^{2015}}+\frac{-7}{2016^{2016}}=\frac{-15.2016}{2016^{2016}}+\frac{-7}{2016^{2016}}=\frac{-30247}{2016^{2016}}\)
Vậy : A>B
So sánh hai phân số : A=\(\frac{2015}{2016}+\frac{2016}{2017}+\frac{2017}{2018}\)và B=\(\frac{2015+2016+2017}{2016+2017+2018}\)
So sánh hai phân số A=\(\frac{2015}{2016}+\frac{2016}{2017}+\frac{2017}{2018}\)và B=\(\frac{2015+2016+2017}{2016+2017+2018}\)
Các bn giải giúp mk nha ! Mk cần gấp ! Thanks nhiều. ^-^
\(\left(\frac{1}{2}+\frac{2015}{2016}+\frac{2016}{2017}+1\right)\left(\frac{2105}{2016}+\frac{2016}{2017}+\frac{7}{22}\right)-\left(\frac{1}{2}+\frac{2015}{2016}+\frac{2016}{2017}\right)\left(\frac{2015}{2016}+\frac{2016}{2017}+\frac{7}{22}+1\right)\)
So Sánh:
A= \(\frac{2015}{2016}+\frac{2016}{2017}\)và B=\(\frac{2015+2016}{2016+2017}\)
So sánh
\(A=\frac{2015}{2016}+\frac{2016}{2017}\) và \(B=\frac{2015+2016}{2016+2017}\)
Cho phân số \(A=\frac{2015^{2016}+2}{2015^{2016}-1}\); \(B=\frac{2015^{2016}}{2015^{2016}-3}\)
So sánh A và B
So sánh 2 phân số sau\(\frac{2014+2015+2016}{2015+2016+2017}\) và \(\frac{2014}{2015}+\frac{2015}{2016}+\frac{2016}{2017}\)
So sánh 2 phân số
A=\(\frac{2015}{2016}+\frac{2016}{2017}+\frac{2017}{2018}\)
B=\(\frac{2015+2016+2017}{2016+2017+2018}\)
Hãy so sánh và B
\(A=\frac{2015}{2016}+\frac{2016}{2017}\) \(B=\frac{2015+2016}{2016=2017}\)
