\(\dfrac{-2019}{2019}=-1\)
\(\dfrac{-2021}{2020}=-1,004\)
\(\Rightarrow\dfrac{-2019}{2019}>\dfrac{-2021}{2020}\)
\(-\dfrac{2019}{2019}=-1\)
\(\dfrac{-2021}{2020}< -1\)
Do đó: \(-\dfrac{2019}{2019}>\dfrac{-2021}{2020}\)
\(\dfrac{-2019}{2019}=-1\)
\(\dfrac{-2021}{2020}=-1,004\)
\(\Rightarrow\dfrac{-2019}{2019}>\dfrac{-2021}{2020}\)
\(-\dfrac{2019}{2019}=-1\)
\(\dfrac{-2021}{2020}< -1\)
Do đó: \(-\dfrac{2019}{2019}>\dfrac{-2021}{2020}\)
A=2017/2018+2020/2019
B=2018/2019+2021/2020
So sánh A và B
so sánh: 2018^2019+1/2018^2020+1 và 2018^2020+1/2018^2021+1
1. So sánh
a) \(A=\dfrac{1}{2}+\dfrac{1}{2^2}+\dfrac{1}{2^3}+...+\dfrac{1}{2^{2020}}+\dfrac{1}{2^{2021}}\) và B= \(\dfrac{1}{3}+\dfrac{1}{4}+\dfrac{1}{5}+\dfrac{13}{60}\)
b) \(C=\dfrac{2019}{2021}+\dfrac{2021}{2022}\) và \(D=\dfrac{2020+2022}{2019+2021}.\dfrac{3}{2}\)
so sánh :
x=2020/2019 và y=2021/2020
lm giúp tui nhanh vs m.n
so sánh : -2020/2019 và -2021/2020
Giúp em với ạ
Em cảm ơn
So sánh
a)\(\frac{-60}{12}\)và -0,8
b) \(\frac{2020}{2019}\)và \(\frac{2021}{2020}\)
c) \(\frac{10^{2018}+1}{10^{2019}+1}\)và \(\frac{10^{2019}+1}{10^{2020+1}}\)
So sánh x = 20192020 + 1 / 20192019 + 1 và y = 20192019 + 2020 / 20192018 + 2020
So sánh :
A=2018×2019/2019×2019+1
B= 2019×2020/2019×2020+1
2018^2019+2019^2020+2020^2021 cia 12 dư bao nhiêu ?
