Q. f(x) = 1x¹ + 2x² + 3x³ f(5) =...Yeyy 10 BA Lagi_.​

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
