প্রদত্ত:

অভিব্যক্তি: \(1+\frac{1}{1+\frac{1}{5+\frac{1}{2+\frac{1}{3}}}}\)

গণনা:

ধাপ 1: সবচেয়ে ভেতরের ভগ্নাংশটি সরলীকরণ করুন

\(2+\frac{1}{3} = \frac{6+1}{3} = \frac{7}{3}\)

ধাপ 2: পরবর্তী ভগ্নাংশে প্রতিস্থাপন করুন

\(5+\frac{1}{\frac{7}{3}} = 5+\frac{3}{7} = \frac{35+3}{7} = \frac{38}{7}\)

ধাপ 3: পরবর্তী ভগ্নাংশে প্রতিস্থাপন করুন

\(1+\frac{1}{\frac{38}{7}} = 1+\frac{7}{38} = \frac{38+7}{38} = \frac{45}{38}\)

ধাপ 4: চূড়ান্ত অভিব্যক্তিতে প্রতিস্থাপন করুন

\(1+\frac{1}{\frac{45}{38}} = 1+\frac{38}{45} = \frac{45+38}{45} = \frac{83}{45}\)

∴ মানটি \(\frac{83}{45}\) = \(1 \frac{38}{45}\)
