Tìm x, biết:
( \(\dfrac{1}{2}\) + \(\dfrac{1}{3}\) + \(\dfrac{1}{4}\) + ... + \(\dfrac{1}{2023}\) ) . x = \(\dfrac{2022}{1}\) + \(\dfrac{2021}{2}\) + \(\dfrac{2020}{3}\)
+ ... + \(\dfrac{1}{2022}\)
Tìm x, biết :
a) \(\dfrac{\text{x}}{3}\) = \(\dfrac{2}{3}\) + \(\dfrac{-1}{7}\)
b) \(\dfrac{-5}{6}-x\) = \(\dfrac{7}{12}+\dfrac{-1}{3}\)
Cho A = \(\dfrac{10^{2020}-1}{10^{2021}-1}\) và B = \(\dfrac{10^{2021}+1}{10^{2022}+1}\)
