Answer 1

2.127

Penjelasan dengan langkah-langkah:

Diketahui:

• x = 1

Ditanya:

• Lim 100x + 78 × 34 - 5x⁴ = ...?

Jawab:

Lim 100x + 78 × 34 - 5x⁴

x = 1

• = 100x + 78 × 34 - 5x⁴
• = 100(1) + 78 × 34 - 5(1)⁴
• = 100(1) + 78 × 34 - 5⁴
• = 100(1) + 78 × 34 - (5.5.5.5)
• = 100(1) + 78 × 34 - (25.25)
• = 100(1) + 78 × 34 - 625
• = 100 + (78 × 34) - 625
• = 100 + (2.652 - 625)
• = 100 + 2.027
• = 2.127

Answer 2

Lim 100x + 78 × 34 - 5x⁴

x = 1

Penyelesaian:

= 100(1) + 78(1) × 34(1) - 5(1)⁴

= (100 × 1) + (78 × 1) × (34 × 1) - (5 × 1)⁴

= 100 + 78 × 34 - 5⁴

= 100 + 78 × 34 - (5 × 5 × 5 × 5)

= 100 + (78 × 34) - 625

= 100 + 2.652 - 625

= 2.752 - 625

= 2.127
