Correct Answer

D. 3m

Explanation

Simple Explanation

गुणनफल का अर्थ दो राशियों को गुणा करना होता है। इसलिए m और 3 का गुणनफल 3 × m = 3m है। m + 3 योग को दर्शाता है, गुणनफल को नहीं। परीक्षा टिप: संख्या और चर के गुणन में गुणा का चिह्न सामान्यतः नहीं लिखा जाता; 3 × m को 3m लिखते हैं। / A product is obtained by multiplying quantities. Thus, the product of m and 3 is 3 × m = 3m. The expression m + 3 represents addition, not multiplication. Exam tip: In algebra, the multiplication sign is usually omitted between a number and a variable, so 3 × m is written as 3m.
