f(x)= (5/x−1)/(5−2/x)  হলে f(1/2) হয় —

Explanation:

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, \(f(\frac{1}{2}) = 9\)। 🎉
