abc = 5 అయితే
ఉపయోగించిన భావన:
⇒ ac = \(5\over b \)
⇒ (b)-1
⇒ b = \(5\over ac\)
లెక్కింపు:
\({1 \over 1 \ + \ a \ + \ b^{-1} }\) + \(\frac{1}{1+\frac{c}{5}+a^{-1}}\) + \(\frac{1}{1+\frac{5}{ac}+5c^{-1}}\)
⇒ \(\frac{1}{1+\frac{ac}{5}+a}\) + \({1 \over 1 \ + \ a \ + \ b^{-1} }\) + \(\frac{1}{1+\frac{1}{ab}+a^{-1}}\)
⇒ \(5\over5+5a+ac \) \(+\) \(ac\over5+5a+ac \) \(+\) \(a\over5+a+ac \)
⇒ \(a+5+ac\over5+a+ac \)
⇒ \(1\)
( \({1 \over 1 \ + \ a \ + \ b^{-1} }\)+\({1 \over 1 \ + \ b \ + \ 5 c^{-1}}\)+\(\frac{1}{1+\frac{c}{5}+a^{-1}}\)) యొక్క విలువ 1
షార్ట్కట్ ట్రిక్a = b = 1 మరియు c = 5 అనుకుందాం
ఇప్పుడు, ప్రశ్న ప్రకారం,
⇒ \(\frac{1}{1+\frac{5}{5}+ {1}}\) \({1 \over 1 \ + \ 1 \ + \ 1}\) + \({1 \over 1 \ + \ 1 \ + {5 \over 5 }}\)
⇒ 1/3 + 1/3 + 1/3
⇒ 3/3 = 1
