Question

If x +1/x = 5 (x ≠ 0), then find the value of x^3 + 1/x^3.
Plz give correct answer with solution.​

Answer 1

Answer:

110

Step-by-step explanation:

x+1/x = 5

(x+1/x)³ = 5³ [cubing both sides]

x³+1/x³+3×x×1/x(x+1/x) = 125

x³+1/x³+3×5 = 125 [as it is given x+1/x = 5]

x³+1/x³+15 = 125

x³+1/x3 = 125–15

x³+1/x³ = 110

Answer 2

Answer:

Question ⤵

If x +1/x = 5 (x ≠ 0), then find the value of x^3 + 1/x^3.

Answer ⬇

x+1/x = 5

(x+1/x)³ = 5³ [cubing both sides]

x³+1/x³+3×x×1/x(x+1/x) = 125

x³+1/x³+3×5 = 125 [as it is given x+1/x = 5]

x³+1/x³+15 = 125

x³+1/x3 = 125–15

x³+1/x³ = 110 ans.
