While my father loves reading, he usually buys his children a tons of books and he knows a lot of things! My brother is a lover for gardening, he plants and takes care of our whole garden.

\(\dfrac{1}{3x}-\dfrac{1}{4x}=\dfrac{1}{x^2}\)

\(\dfrac{4x-3x}{4x3x}=\dfrac{1}{x^2}\)

\(\dfrac{1}{12x}=\dfrac{1}{x^2}\)

\(\Rightarrow12x=x.x\)

\(\Rightarrow12=x\)

Vậy \(x=12\)

\(\dfrac{2}{3}x-\dfrac{1}{2}x=\dfrac{3}{4x^2}\)

\(\dfrac{4x-3x}{3.2}=\dfrac{3}{4x^2}\)

\(\dfrac{1}{2}=\dfrac{1}{4x}\)

\(\Rightarrow2=4x\)

\(\Rightarrow x=\dfrac{2}{4}\)

Vậy \(x=\dfrac{2}{4}\)

\(\dfrac{5}{4\times9}+\dfrac{5}{9\times14}+\dfrac{5}{14\times19}+...+\dfrac{5}{2024\times2019}\)

\(=\dfrac{9-4}{4\times9}+\dfrac{14-9}{9\times14}+\dfrac{19-14}{14\times19}+...+\dfrac{2024-2019}{2024\times2019}\)\(=\dfrac{9}{4\times9}-\dfrac{4}{4\times9}+\dfrac{14}{9\times14}-\dfrac{9}{9\times14}+...+\dfrac{2024}{2024\times2019}-\dfrac{2019}{2024\times2019}\)

\(=\dfrac{1}{4}-\dfrac{1}{9}+\dfrac{1}{9}-\dfrac{1}{14}+...+\dfrac{1}{2019}-\dfrac{1}{2024}\)

\(=\dfrac{1}{4}-\dfrac{1}{2024}\)

Ta đặt các số đó dạng: \(\overline{ab6}\)

- Trong đó b có 10 lựa chọn (từ 0 - 9)

- Trong đó a có 9 lựa chọn (từ 1 - 9)

Mà tận cùng chỉ có thể = 6 nên ta có số số là:

10 x 9 x 1 = 90 (số)

Đáp số: 90 số
