If (x) is an irrational number, which statement about (-x) is correct?यदि (x) एक अपरिमेय संख्या है, तो (-x) के बारे में सही कथन क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: It is always irrationalयह हमेशा अपरिमेय है
Step 1: A negative sign changes direction, not rationality. Step 2: If (-x) were rational, then (x) would also be rational, which is false. Step 3: Treat the sign of a number and its type separately.चरण 1: ऋण चिह्न केवल संख्या की दिशा बदलता है, उसकी परिमेयता नहीं। चरण 2: यदि (-x) परिमेय हो, तो (x) भी परिमेय होगा, जो गलत है। चरण 3: संख्या के चिह्न और संख्या की प्रकृति को अलग-अलग समझें।
