Q. f(x) = 1x¹ + 2x² + 3x³ f(5) =…Yeyy 10 BA Lagi_.
430
Penjelasan dengan langkah-langkah:
f(x) = 1x¹ + 2x² + 3x³
f(5) = 1(5¹) + 2(5²) + 3(5³)
f(5) = 1(5) + 2(25) + 3(125)
f(5) = 5 + 50 + 375
f(5) = 55 + 375
f(5) = 430

Jawab
- f(x) = 1x¹ + 2x² + 3x³
- f(5) = 1(5¹) + 2(5²) + 3(5³)
- f(5) = 1(5) + 2(5²) + 3(5³)
- f(5) = 1(5) + 2(5 × 5) + 3(5³)
- f(5) = 1(5) + 2(25) + 3(5³)
- f(5) = 1(5) + 2(25) + 3(5 × 5 × 5)
- f(5) = 1(5) + 2(25) + 3(25 × 5)
- f(5) = 1(5) + 2(25) + 3(125)
- f(5) = (1 × 5) + 2(25) + 3(125)
- f(5) = 5 + 2(25) + 3(125)
- f(5) = 5 + (25 + 25) + 3(125)
- f(5) = 5 + 50 + 3(125)
- f(5) = 55 + 3(125)
- f(5) = 55 + (125 + 125 + 125)
- f(5) = 55 + (250 + 125)
- f(5) = 55 + 375
- f(5) = 430
