Step-by-step explanation:
x + 1/x = 5 --------(1)
Doing square both side
x² + 1/x² + 2 = 25
x² + 1/x² = 23 -------(2)
Doing cube both side of equation (1)
x³ + 1/x³ + 3(x + 1/x) = (5)³
x³ + 1/x³ + 3(5) = 125
x³ + 1/x³ = 125 - 15
x³ + 1/x³ = 110 --------(3)
From equation (2) × (3)
(x² + 1/x²) × (x³ + 1/x³) = 23 × 110
x^5 + 1/x + x + 1/x^5 = 2530
x^5 + 1/x^5 + (x + 1/x) = 2530
x^5 + 1/x^5 = 2530 - 5
= 2525
