यदि \(a\neq0\) और (b=0), तो \(ax^4+bx^6+3\) की डिग्री क्या होगी?
If \(a\neq0\) and (b=0), what will be the degree of \(ax^4+bx^6+3\)?
Explanation opens after your attempt
Correct Answer
B. (4)
Concept
Since (b=0), the \(x^6\) term disappears, and since \(a\neq0\), the \(x^4\) term remains. So the degree is (4).
Why this answer is correct
The correct answer is B. (4). Since (b=0), the \(x^6\) term disappears, and since \(a\neq0\), the \(x^4\) term remains. So the degree is (4).
Exam Tip
(b=0) होने से \(x^6\) पद हट जाता है और \(a\neq0\) से \(x^4\) पद बचता है। इसलिए डिग्री (4) है।
