What is the value of (13^2 + 3^4)?(13^2 + 3^4) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 250250
13^2 = 13 × 13 = 169 and 3^4 = 3 × 3 × 3 × 3 = 81. Therefore (13^2 + 3^4) = 169 + 81 = 250. Option A (240) is incorrect — it likely arises from an arithmetic mistake (for example, computing 3^4 incorrectly). Exam tip: evaluate each power separately, then add and recheck the addition to avoid simple errors.13^2 = 13 × 13 = 169 और 3^4 = 3 × 3 × 3 × 3 = 81। अतः (13^2 + 3^4) = 169 + 81 = 250। विकल्प A (240) गलत है — यह किसी गणना त्रुटि का परिणाम हो सकता है (उदाहरण के लिए 3^4 को गलत‑तौर पर 71 माना जाना)। परीक्षा सलाह: घातों को अलग‑अलग चरणबद्ध रूप से निकालें और फिर जोड़कर उत्तर की जाँच करें।
