106 × 106 + 94 × 94 = ? 106 × 106 + 94 × 94 = ? Explanationव्याख्या: 106 = 100+6 94 = 100−6 Using: (a+b)²+(a−b)² = 2(a²+b²) Therefore, 106² + 94² = 2(100² + 6²) = 2(10000+36) = 2×10036 = 20072Same topic · Same subject · Same exam

14927 × 567 − 14927 × 467 = ? 14927 × 567 − 14927 × 467 = ? Explanationव्याख्या: Take 14927 common: 14927×567 − 14927×467 = 14927(567−467) = 14927×100 = 1492700Same topic · Same subject · Same exam

469157 × 9999 = ? 469157 × 9999 = ? Explanationव्याख्या: 9999 = 10000 − 1 Therefore, 469157 × 9999 = 469157 × (10000−1) = 4,691,570,000 − 469,157 = 4,691,100,843 Therefore, Answer = 4691100843Same topic · Same subject · Same exam

If the unit digit in (549 × 56 × 28* × 684) is 8, then what digit will be there in place of *? We only need unit digits: 549 → 9 56 → 6 28* → * 684 → 4 Therefore, 9 × 6 × * × 4 First, 9 × 6 × 4 = 216 So we need the unit digit of: 216 × * Since 216 ends in 6, we need: 6 × * to end in 8. Check options: 6 × 4 = 24 → unit digit 4 6 × 3 = 18 → unit digit 8 6 × 2 = 12 → unit digit 2 6 × 1 = 6 Therefore, = 3 Divisibility and Remainderयदि (549 × 56 × 28 × 684) का इकाई अंक 8 है, तो * के स्थान पर कौन-सा अंक होगा?* Explanation व्याख्या: Here 28* represents a three-digit number whose unit digit is *.Same topic · Same subject · Same exam

Explanation Cycle of 7: 7, 9, 3, 1 764 ÷ 4 = 191 with remainder 0. When remainder is 0, we take the fourth number of the cycle. Therefore, unit digit = 1.The digit in the unit place of (2137)⁷⁶⁴ is: (2137)⁷⁶⁴ का इकाई अंक क्या है? व्याख्या: Only the last digit 7 matters.Same topic · Same subject · Same exam

Explanation 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 (7⁹⁵ − 3⁵⁸) is: (7⁹⁵ − 3⁵⁸) का इकाई अंक क्या है? व्याख्या: For 7⁹⁵: Cycle = 7, 9, 3, 1 95 ÷ 4 leaves remainder 3.Same topic · Same subject · Same exam
