Question : If ${P}+\frac{1}{{P}}=5$, then what is the value of ${P}^3+\frac{1}{{P}^3}$?
Option 1: 110
Option 2: 95
Option 3: 125
Option 4: 120
Correct Answer: 110
Solution : ${P}+\frac{1}{{P}}=5$ Cubing both sides, we get, $(a+b)^3 = a^3 + b^3 + 3ab(a+b)$ ⇒ $({P}+\frac{1}{{P}})^3=5^3$ ⇒ $P^3 + \frac{1}{P^3} + 3(P+\frac{1}{P})=125$ ⇒ $P^3 + \frac{1}{P^3} + 3(5)= 125$ ⇒ $P^3+\frac{1}{P^3}= 125-15$ ⇒ $P^3 + \frac{1}{P^3} = 110$ Hence, the correct answer is 110.
