\(\frac{{5{\rm{x}}}}{{1{\rm{\;}} + {\rm{\;}}\frac{1}{{1{\rm{\;}} + {\rm{\;}}\frac{{\rm{x}}}{{1{\rm{\;}} - {\rm{\;x}}}}}}}}{\rm{\;}} = {\rm{\;}}1\)
গণনা:
\(\Rightarrow {\rm{\;}}\frac{{5{\rm{x}}}}{{1{\rm{\;}} + {\rm{\;}}\frac{{1 - {\rm{x}}}}{{1 - {\rm{x\;}} + {\rm{\;x}}}}}}{\rm{\;}} = {\rm{\;}}1 \)
\(\Rightarrow {\rm{\;}}\frac{{5{\rm{x}}}}{{1{\rm{\;}} + {\rm{\;}}1 - {\rm{x}}}}{\rm{\;}} = {\rm{\;}}1\)
⇒ 5x/(2 - x) = 1
⇒ 5x = 2 - x
⇒ 6x = 2
⇒ x = 2/6
∴ x-এর প্রয়োজনীয় মান 1/3.
