যদি \(\frac{{5{\rm{x}}}}{{1{\rm{\;}} + {\rm{\;}}\frac{1}{{1{\rm{\;}} + {\rm{\;}}\frac{{\rm{x}}}{{1{\rm{\;}} - {\rm{\;x}}}}}}}}{\rm{\;}} = {\rm{\;}}1\) হয়, তাহলে 'x'-এর মান নির্ণয় করো।

প্রদত্ত:

\(\frac{{5{\rm{x}}}}{{1{\rm{\;}} + {\rm{\;}}\frac{1}{{1{\rm{\;}} + {\rm{\;}}\frac{{\rm{x}}}{{1{\rm{\;}} - {\rm{\;x}}}}}}}}{\rm{\;}} = {\rm{\;}}1\)

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.
