The expression x + x + x + x is equal to which of the following?व्यंजक x + x + x + x किसके बराबर है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 4x4x
Since x is added four times, x + x + x + x = 4x. Repeated addition of the same term is written as multiplication: four copies of x equal 4 times x.x को चार बार जोड़ा गया है, इसलिए x + x + x + x = 4x। एक ही पद के बार-बार जोड़ को गुणा के रूप में लिखते हैं: x की चार प्रतियाँ, 4 गुना x के बराबर होती हैं।
