व्यंजक (0.3 - 0.2) (0.32 + 0.3 × 0.2 + 0.22) को सरल करना है।
प्रयुक्त सूत्र:
मूल अंकगणितीय संक्रियाओं और बीजीय सर्वसमिकाओं का उपयोग करने पर:
(a - b)(a2 + ab + b2) = a3 - b3
गणना:
दिया गया व्यंजक: (0.3 - 0.2) (0.32 + 0.3 × 0.2 + 0.22)
सबसे पहले, आंतरिक व्यंजक को सरल बनाते हैं:
0.32 + 0.3 × 0.2 + 0.22
0.09 + 0.06 + 0.04
0.19
अब, बाह्य व्यंजक को सरल करते हैं:
(0.3 - 0.2) × 0.19
0.1 × 0.19
