(\(\sqrt{29}+5\)2-\(\sqrt{29}-5\)2) का मान क्या है?
What is the value of (\(\sqrt{29}+5\)2-\(\sqrt{29}-5\)2)?
Explanation opens after your attempt
Correct Answer
B. \(20\sqrt{29}\)
Concept
Use ((a+b)2-(a-b)2=4ab). Here \(a=\sqrt{29}\) and (b=5), so the value is \(20\sqrt{29}\).
Why this answer is correct
The correct answer is B. \(20\sqrt{29}\). Use ((a+b)2-(a-b)2=4ab). Here \(a=\sqrt{29}\) and (b=5), so the value is \(20\sqrt{29}\).
Exam Tip
पहचान ((a+b)2-(a-b)2=4ab) लगाएं। यहाँ \(a=\sqrt{29}\) और (b=5), इसलिए मान \(20\sqrt{29}\) है।
