Q: Find the value of (10001+12) (10001–12). (10001 + 12) (10001 – 12) का मान ज्ञात कीजिए।
  • A. 1000190857
  • B. 1000019857
  • C. 100019857
  • D. 10019857
Correct Answer: Option C - (10001 + 12) (10001 – 12) = (10001)²–(12)² [ ∴ (a+b)(a–b) = a²–b²] = 100,020,001–144 = 100019857
C. (10001 + 12) (10001 – 12) = (10001)²–(12)² [ ∴ (a+b)(a–b) = a²–b²] = 100,020,001–144 = 100019857

Explanations:

(10001 + 12) (10001 – 12) = (10001)²–(12)² [ ∴ (a+b)(a–b) = a²–b²] = 100,020,001–144 = 100019857
