Find ((9^{1/2}+16^{1/2})^2).((9^{1/2}+16^{1/2})^2) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 4949
Here, (9^{1/2}=\sqrt{9}=3) and (16^{1/2}=\sqrt{16}=4). Therefore, ((3+4)^2=7^2=49). Hence, 49 is correct. Exam tip: convert an exponent of 1/2 into a square root first, simplify the terms, and then square their sum.यहाँ (9^{1/2}=\sqrt{9}=3) और (16^{1/2}=\sqrt{16}=4) हैं। इसलिए ( (3+4)^2=7^2=49 )। अतः सही उत्तर 49 है। परीक्षा-युक्ति: पहले घात 1/2 को वर्गमूल में बदलकर सरल करें, फिर प्राप्त योग का वर्ग करें।
