कौन-सा विकल्प \(L=\{1,8,27,64,125\}\) को सही ढंग से दर्शाता है?
Which option correctly represents \(L=\{1,8,27,64,125\}\)?
Explanation opens after your attempt
A. \(L={x:x=n^3,,n\in \mathbb{N},,1\leq n\leq 5}\)
Concept
(1,8,27,64,125) are \(1^3,2^3,3^3,4^3,5^3\).
Why this answer is correct
Therefore the rule is \(x=n^3\).
Exam Tip
To get exactly five elements, the bound \(1\leq n\leq 5\) is needed. चरण 1: (1,8,27,64,125) क्रमशः \(1^3,2^3,3^3,4^3,5^3\) हैं। चरण 2: इसलिए नियम \(x=n^3\) होगा। चरण 3: ठीक पाँच अवयव पाने के लिए \(1\leq n\leq 5\) सीमा लगानी होगी।
