यदि (p(x)=x-2-7) है, तो (p\(\sqrt{7}+1\)) का मान किस रूप में है?
If (p(x)=x-2-7), what is the form of (p\(\sqrt{7}+1\))?
Explanation opens after your attempt
A. \(1+2\sqrt{7}\)
Concept
(\(\sqrt{7}+1\)2-7=8+2\sqrt{7}-7=1+2\sqrt{7}). Use ((a+b)2) carefully in exams.
Why this answer is correct
The correct answer is A. \(1+2\sqrt{7}\). (\(\sqrt{7}+1\)2-7=8+2\sqrt{7}-7=1+2\sqrt{7}). Use ((a+b)2) carefully in exams.
Exam Tip
(\(\sqrt{7}+1\)2-7=8+2\sqrt{7}-7=1+2\sqrt{7}) है। परीक्षा में ((a+b)2) सावधानी से लगाएं।
