यदि (m=0), तो (mx-4+(m+2)x-3-5) की डिग्री क्या होगी?

If (m=0), what will be the degree of (mx-4+(m+2)x-3-5)?

Explanation opens after your attempt
Correct Answer

B. (3)

Step 1

Concept

Putting (m=0) removes the \(x^4\) term and leaves \(2x^3-5\). Therefore the degree is (3).

Step 2

Why this answer is correct

The correct answer is B. (3). Putting (m=0) removes the \(x^4\) term and leaves \(2x^3-5\). Therefore the degree is (3).

Step 3

Exam Tip

(m=0) रखने पर \(x^4\) पद हट जाता है और \(2x^3-5\) बचता है। इसलिए डिग्री (3) है।
