Q: Simplify the expression: (0.2)³ + (0.5)³ + (0.7)³ – (4 × 0.2 × 0.5 × 0.7) व्यंजक (0.2)³ + (0.5)³ + (0.7)³– (4 × 0.2 × 0.5 × 0.7) का सरलीकृत मान ज्ञात कीजिए।
  • A. 0.196
  • B. 1.96
  • C. 19.60
  • D. 0.0196
Correct Answer: Option A - (0.2)³ + (0.5)³ + (0.7)³ – (4 × 0.2 × 0.5 × 0.7) = 0.008 + 0.125 + 0.343 –0.280 = 0.476 –0.280 = 0.196
A. (0.2)³ + (0.5)³ + (0.7)³ – (4 × 0.2 × 0.5 × 0.7) = 0.008 + 0.125 + 0.343 –0.280 = 0.476 –0.280 = 0.196

Explanations:

(0.2)³ + (0.5)³ + (0.7)³ – (4 × 0.2 × 0.5 × 0.7) = 0.008 + 0.125 + 0.343 –0.280 = 0.476 –0.280 = 0.196
