WebIf x+ 1 x= 5, find the value of x3+ 1 x3. Solution We have, x+ 1 x= 5 on Cubing both sides, we get (x+ 1 x)3 = (5)3 ⇒ x3+ 1 x3 +3×x× 1 x(x+ 1 x)= 125 [ ∵ (a+b)3 = a3+b3+3ab(a+b)] ⇒ …
Webx − 1 x = 5. Cubing both sides (x − 1 x) 3 = (5) 3 ⇒ x 3 − 1 x 3 − 3 (x − 1 x) = 125 ⇒ x 3 − 1 x 3 − 3 × 5 = 125 ⇒ x 3 − 1 x 3 − 15 = 125 ⇒ x 3 − 1 x 3 = 125 + 15 = 140 ∴ x 3 − 1 x 3 = 140 geoff hussonWebEffie Company uses a periodic inventory system.
