x - (1/x) = (- 6)
ഉപയോഗിച്ച സൂത്രവാക്യം:
x - (1/x) = P ആണെങ്കിൽ,
x + (1/x) = √(P2 + 4)
x + (1/x) = P ആണെങ്കിൽ,
x 3 + (1/x 3 ) = (P 3 - 3P)
x 5 - (1/x 5 ) = {x 3 + (1/x 3 )} × {x 2 - 1/x 2 } + {x - (1/x)}
കണക്കുകൂട്ടല്:
x - (1/x) = (- 6)
x + (1/x) = √{(- 6) 2 + 4} = √40 = 2√10
അതിനാൽ , x 2 - 1/x 2 = (x + 1/x) (x - 1/x) = 2 √10 × (-6) = -12√10
കൂടാതെ x 3 + (1/x 3 ) = (√40) 3 - 3 √40
⇒ 40√40 - 3√40 = 37 × 2√10 = 74√10
ഇപ്പോൾ,
x 5 - (1/x 5 ) = {x 3 + (1/x3 )} × {x 2 - 1/x 2 } + {x - (1/x)}
⇒ {74√10 × (-12√10) } + (- 6)
⇒ - 74 × 12 × ( √10 × √10) - 6
⇒ (- 8880) - 6 = - 8886
∴ ശരിയായ ഉത്തരം - 8886 ആണ്.
