\(यदि (V_1={x:x\in \mathbb{N},,x<100,,x\) is a square and a cube\(}), तो (V_1) क्या है\)?
\(If (V_1={x:x\in \mathbb{N},,x<100,,x\) is a square and a cube\(}), what is (V_1)\)?
Correct answer and explanation
A. \(V_1={1,64}\)
Concept
जो संख्या वर्ग और घन दोनों हो, वह छठी घात होती है। / A number that is both a square and a cube is a sixth power.
Why this answer is correct
(100) से छोटी छठी घातें \(1^6=1\) और \(2^6=64\) हैं। / Sixth powers less than (100) are \(1^6=1\) and \(2^6=64\).
Exam Tip
दोनों शर्तों को अलग-अलग नहीं, साथ में पूरा करना होता है। / Both conditions must be satisfied together, not separately.
