Question.
Jawaban:
5x × 10x + 7x – 12x²
x = 5
- (5×5) × 10(5) + 7(5) – 12(5²)
- 25 × 50 + 35 – 12(5×5)
- 25 × 50 + 35 – 12(25)
- 25 × 50 + 35 – 300
- 1.250 + 35 – 300
- 1.285 – 300
- 985
Penjelasan dengan langkah-langkah:
Lim ( 5x × 10x + 7x – 12x² )
x → 5
= 5x × 10x + 7x – 12x²
= 5.5 × 10.5 + 7.5 – 12.5²
= 25 × 50 + 35 – 12.25
= 25 × 50 + 35 – 300
= 1.250 + 35 – 300
= 1.285 – 300
= 985
