Which one of the following will divide (4⁶¹ + 4⁶² + 4⁶³ + 4⁶⁴) completely? निम्नलिखित में से कौन (4⁶¹ + 4⁶² + 4⁶³ + 4⁶⁴) को पूर्णतः विभाजित करेगा? Explanation / व्याख्या: Take 4⁶¹ common: 4⁶¹ + 4⁶² + 4⁶³ + 4⁶⁴ = 4⁶¹(1 + 4 + 4² + 4³) = 4⁶¹(1 + 4 + 16 + 64) = 4⁶¹ × 85 Now, 85 = 5 × 17 Also, 4⁶¹ contains factor 2. Therefore, the complete expression contains both 2 and 5. 2 × 5 = 10 Hence it is divisible by 10.
The unit digit in (584 × 428 × 667 × 213) is: (584 × 428 × 667 × 213) का इकाई अंक क्या है? Explanation / व्याख्या: Only unit digits are required: 4 × 8 × 7 × 3 4 × 8 = 32 → unit digit 2 2 × 7 = 14 → unit digit 4 4 × 3 = 12 → unit digit 2 Therefore, answer = 2.
The unit digit in (7⁹⁵ − 3⁵⁸) is: (7⁹⁵ − 3⁵⁸) का इकाई अंक क्या है? Explanation / व्याख्या: For 7⁹⁵: Cycle = 7, 9, 3, 1 95 ÷ 4 leaves remainder 3. Therefore, unit digit = 3. For 3⁵⁸: Cycle = 3, 9, 7, 1 58 ÷ 4 leaves remainder 2. Therefore, unit digit = 9. We need the unit digit of: 7⁹⁵ − 3⁵⁸ At the unit place: 3 − 9 Borrow 10: 13 − 9 = 4 Therefore, unit digit = 4.
The unit digit in (3⁶⁵ × 6⁵⁹ × 7⁷¹) is: (3⁶⁵ × 6⁵⁹ × 7⁷¹) का इकाई अंक क्या है? Explanation / व्याख्या: For 3⁶⁵: Unit digit cycle of 3 = 3, 9, 7, 1 65 ÷ 4 leaves remainder 1. Therefore, unit digit of 3⁶⁵ = 3. For 6⁵⁹: Every positive power of 6 ends in 6. Therefore, unit digit = 6. For 7⁷¹: Cycle = 7, 9, 3, 1 71 ÷ 4 leaves remainder 3. Therefore, unit digit = 3. Now, 3 × 6 × 3 = 54 Unit digit = 4
The difference between the place values of 8 in the numeral 6283481 is: संख्या 6283481 में दोनों 8 के स्थानीय मानों का अंतर कितना है?

Place value = 80 Difference = 80000 − 80 = 79920 पहले 8 का स्थानीय मान = 80000 दूसरे 8 का स्थानीय मान = 80 अंतर = 80000 − 80 = 79920 Unit Digit
The place value of 7 in the numeral 634721 is: संख्या 634721 में अंक 7 का स्थानीय मान क्या है? Explanation / व्याख्या: In 634721, 7 is at the hundreds place. Place value = 7 × 100 = 700 634721 में 7 सैकड़े के स्थान पर है। स्थानीय मान = 7 × 100 = 700
The difference between the local value and face value of 6 in the numeral 586723 is: संख्या 586723 में अंक 6 के स्थानीय मान और अंकित मान के बीच का अंतर कितना है? Explanation / व्याख्या: In 586723, digit 6 is at the thousands place. Place value of 6 = 6 × 1000 = 6000 Face value of 6 = 6 Difference = 6000 − 6 = 5994 संख्या 586723 में 6 हजार के स्थान पर है। 6 का स्थानीय मान = 6 × 1000 = 6000 6 का अंकित मान = 6 अंतर = 6000 − 6 = 5994
