দেয়া আছে, p + 1/p = 5
আমরা জানি, (a + b)3 = a3 + b3 + 3ab(a + b)
তাহলে, (p + 1/p)3 = p3 + 1/p3 + 3*p*1/p* (p + 1/p)
বা, (p + 1/p)3 = p3 + 1/p3 + 3(p + 1/p)
বা, p3 + 1/p3 = (p + 1/p)3 - 3(p + 1/p) - - - - - - - - - - - - - [পক্ষ পরিবর্তন করে ]
= 53 - 3*5 - - - - - - - - - - - - - - - - - - - - - - - [ (p + 1/p) = 5 মান বসিয়ে ]
= 125 - 15
সুতরাং, p3 + 1/p3 = 110 (Ans:)
