What is the value of \(104^2\)?\(104^2\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 1081610816
\(104^2=(100+4)^2=100^2+2(100)(4)+4^2=10000+800+16=10816\). Therefore, the correct answer is 10816. The nearby distractor 10840 is incorrect because the sum of the middle term 800 and the last term 16 is 816, not 840. Exam tip: Always include the middle term \(2ab\) when using \((a+b)^2=a^2+2ab+b^2\).\(104^2=(100+4)^2=100^2+2(100)(4)+4^2=10000+800+16=10816\)। इसलिए सही उत्तर 10816 है। 10840 गलत है, क्योंकि मध्य पद 800 और अंतिम पद 16 का योग 816 होता है, 840 नहीं। परीक्षा-युक्ति: \((a+b)^2=a^2+2ab+b^2\) में मध्य पद \(2ab\) अवश्य लिखें।
