Another Explanation (5):
bài toán: \(f(x)= \frac{\frac{5}{x}-1}{5-\frac{2}{x}}\) হলে \(f(\frac{1}{2})\) = ?
সমাধান: 🤓
দেওয়া আছে, \(f(x)= \frac{\frac{5}{x}-1}{5-\frac{2}{x}}\)
সুতরাং, \(f(\frac{1}{2}) = \frac{\frac{5}{\frac{1}{2}}-1}{5-\frac{2}{\frac{1}{2}}}\) 🧐
\( = \frac{5 \times 2 - 1}{5 - 2 \times 2}\) 🤩
\( = \frac{10 - 1}{5 - 4}\) 🤔
\( = \frac{9}{1}\) 🥳
\( = 9\) 😎
অতএব, \(f(\frac{1}{2}) = 9\)। 🎉
