यदि (u=2) और (v=-5), तो \(u^2v+uv^2-3u\) का मान क्या होगा?
If (u=2) and (v=-5), what is the value of \(u^2v+uv^2-3u\)?
Explanation opens after your attempt
B. (24)
Concept
Substitution gives (4(-5)+2(25)-6=24). \(v^2\) will be positive.
Why this answer is correct
The correct answer is B. (24). Substitution gives (4(-5)+2(25)-6=24). \(v^2\) will be positive.
Exam Tip
मान रखने पर (4(-5)+2(25)-6=24) मिलता है। \(v^2\) धनात्मक होगा।
