A number leaves remainder 8 when divided by 13. What is the remainder when its square is divided by 13?किसी संख्या को 13 से भाग देने पर शेषफल 8 है। उसी संख्या के वर्ग को 13 से भाग देने पर शेषफल क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 1212
Step 1: For the square, take (8^2=64). Step 2: (64=13\times4+12), so the remainder is 12. Step 3: Do not write 64 as the final answer because a remainder must be smaller than the divisor.चरण 1: वर्ग के लिए (8^2=64) लें। चरण 2: (64=13\times4+12), इसलिए शेषफल 12 है। चरण 3: अंतिम उत्तर में 64 नहीं लिखें, क्योंकि शेषफल भाजक से छोटा होना चाहिए।
