यदि (u=-1) और (v=3), तो \(u^2v-uv^2+2u\) का मान क्या होगा?
If (u=-1) and (v=3), what is the value of \(u^2v-uv^2+2u\)?
Explanation opens after your attempt
B. (10)
Concept
Substitution gives (1(3)-(-1)(9)+2(-1)=10). Find the sign of \(uv^2\) carefully.
Why this answer is correct
The correct answer is B. (10). Substitution gives (1(3)-(-1)(9)+2(-1)=10). Find the sign of \(uv^2\) carefully.
Exam Tip
मान रखने पर (1(3)-(-1)(9)+2(-1)=10) मिलता है। \(uv^2\) के चिह्न को सावधानी से निकालें।
