রাশিমালা \(p-\frac{1}{p}=6\)
অনুসৃত সূত্র:
a2 + b2 = (a - b)2+ 2ab
গণনা:
p4 + \(\frac{1}{p^4}\)
⇒ (p2+\(\frac{1}{p^2}\))2 - 2 × p2 × \(\frac{1}{p^2}\)
⇒ {(p-\(\frac{1}{p}\))2+ (2 × p × \(\frac{1}{p}\))}2 - 2
⇒ {(6)2 + 2}2 - 2
⇒ (36 + 2)2 - 2
⇒ (38)2 - 2
⇒ 1444 - 2
⇒ 1442
সুতরাং রাশিমালা p4 +\(\frac{1}{p^4}\) এর মান হল 1442
