\(y+y+y+\dfrac{1}{2}\times\dfrac{2}{5}\times y+\dfrac{8}{10}=136\\ y\times\left(1+1+1+\dfrac{1}{5}\right)=136-\dfrac{8}{10}=\dfrac{676}{5}\\ y\times\dfrac{16}{5}=\dfrac{676}{5}\\ y=\dfrac{676}{5}:\dfrac{16}{5}=\dfrac{169}{4}\)

Hình như bạn chép sai đề, mình sửa nhé :

\(S=\dfrac{5^2}{1.6}+\dfrac{5^2}{6.11}+\dfrac{5^2}{11.16}+...+\dfrac{5^2}{26.31}\\ =>\dfrac{S}{5}=\dfrac{5}{1.6}+\dfrac{5}{6.11}+\dfrac{5}{11.16}+...+\dfrac{5}{26.31}\\ =>\dfrac{S}{5}=\dfrac{6-1}{1.6}+\dfrac{11-6}{6.11}+\dfrac{16-11}{11.16}+...+\dfrac{31-26}{26.31}\\ =>\dfrac{S}{5}=1-\dfrac{1}{6}+\dfrac{1}{6}-\dfrac{1}{11}+\dfrac{1}{11}-\dfrac{1}{16}+...+\dfrac{1}{26}-\dfrac{1}{31}=1-\dfrac{1}{31}=\dfrac{30}{31}\\ =>S=\dfrac{30}{31}.5=\dfrac{150}{31}\)

\(\left(\dfrac{1}{2.3}+\dfrac{1}{3.4}+\dfrac{1}{4.5}+...+\dfrac{1}{98.99}+\dfrac{1}{99.100}\right).x=\dfrac{1}{5}\\ =>\left(\dfrac{1}{2}-\dfrac{1}{3}+\dfrac{1}{3}-\dfrac{1}{4}+\dfrac{1}{4}-\dfrac{1}{5}+...+\dfrac{1}{98}-\dfrac{1}{99}+\dfrac{1}{99}-\dfrac{1}{100}\right).x=\dfrac{1}{5}\\ =>\left(\dfrac{1}{2}-\dfrac{1}{100}\right).x=\dfrac{1}{5}\\ =>\dfrac{49}{100}.x=\dfrac{1}{5}\\ =>x=\dfrac{1}{5}:\dfrac{49}{100}=\dfrac{1}{5}.\dfrac{100}{49}\\ =>x=\dfrac{20}{49}\)

Online learning has become increasingly popular due to its convenience and comfort. Students have more freedom to learn at their own pace and in their own environment. This independence can be beneficial for those who struggle with traditional classroom settings. However, online learning can also be difficult to concentrate on, with many distractions on the internet. There is also no real interaction with teachers or classmates, which can lead to a lack of motivation and engagement. Additionally, online learning can be harmful to the eyes due to prolonged screen time. It also requires expensive equipment and a reliable internet connection, which can be a financial burden for some students.
