यदि (a=2) और (b=-3), तो \(a^2b-ab^2\) का मान क्या होगा?
If (a=2) and (b=-3), what is the value of \(a^2b-ab^2\)?
Explanation opens after your attempt
A. (-30)
Concept
Substitution gives (4(-3)-2(9)=-12-18=-30). \(b^2\) will be positive.
Why this answer is correct
The correct answer is A. (-30). Substitution gives (4(-3)-2(9)=-12-18=-30). \(b^2\) will be positive.
Exam Tip
मान रखने पर (4(-3)-2(9)=-12-18=-30) मिलता है। \(b^2\) धनात्मक होगा।
