If (q<5), what is the correct result after multiplying both sides by (-2)?यदि (q<5) है तो दोनों ओर (-2) से गुणा करने पर सही परिणाम क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (-2q>-10)(-2q>-10)
Multiplying by a negative number reverses the inequality sign. While multiplying by (-2), changing the direction is necessary.ऋणात्मक संख्या से गुणा करने पर असमानता का चिह्न पलटता है। (-2) से गुणा करते समय दिशा बदलना जरूरी है।
