(\(\sqrt{17}+3\)2-\(\sqrt{17}-3\)2) का मान क्या है?
What is the value of (\(\sqrt{17}+3\)2-\(\sqrt{17}-3\)2)?
Explanation opens after your attempt
Correct Answer
A. \(12\sqrt{17}\)
Concept
Use ((a+b)2-(a-b)2=4ab). Here \(a=\sqrt{17}\) and (b=3), so the value is \(12\sqrt{17}\).
Why this answer is correct
The correct answer is A. \(12\sqrt{17}\). Use ((a+b)2-(a-b)2=4ab). Here \(a=\sqrt{17}\) and (b=3), so the value is \(12\sqrt{17}\).
Exam Tip
पहचान ((a+b)2-(a-b)2=4ab) लगाएं। यहाँ \(a=\sqrt{17}\) और (b=3), इसलिए मान \(12\sqrt{17}\) है।
