B = \(\dfrac{2021\times13+2007+2020\times2007}{2020+2020\times520+1500\times2020}\)
B = \(\dfrac{2021\times13+2007\times\left(1+2020\right)}{2020\times\left(1+520+1500\right)}\)
B = \(\dfrac{2021\times13+2007\times2021}{2020\times2021}\)
B = \(\dfrac{2021\times\left(13+2007\right)}{2021\times2020}\)
B = \(\dfrac{2021\times2020}{2021\times2020}\)
B = 1
\(\dfrac{2018\times2020+2020\times2022}{2020\times4040}\)
tìm B = 2021 x 13 + 2009 + 2020 x 2007 / 2020 + 2020 x 520 x 2020
\(\dfrac{1}{2019}+\dfrac{1}{2020}+\dfrac{1}{2021}\)=?
A = 2020 * 2021
_____________
2020 * 2021 + 1
và B = 2020
_______
2021
hãy so sánh A và B
\(\dfrac{2021x13+2007+2020x2007}{2020+2020x520+1500x2020}\)
Tính nhanh: (2022 x 2021 – 2021 x 2020) x( 1 + \(\dfrac{1}{2}\) : \(1\dfrac{1}{2}\) - \(1\dfrac{1}{3}\) )
\(\dfrac{1}{2019-x}+\dfrac{1}{2020-x}+\dfrac{1}{2021-x}=\dfrac{13}{12}\)
