Q? Last!

Jawaban:

f(x) = x⁵ + 5x × 5

x = 5

_____________

f(5) = 5⁵ + 5(5) × 5

f(5) = (5×5×5×5×5) + 25 × 5

f(5) = (25×5×5×5) + 25 × 5

f(5) = (125×5×5) + 25 × 5

f(5) = (625×5) + 25 × 5

f(5) = 3.125 + 25 × 5

f(5) = 3.125 + 125

f(5) = 3.250

3.250

Penjelasan dengan langkah-langkah:

Diketahui:

  • x = 5

Ditanya:

  • f(x) = x⁵ + 5x × 5 = … ?

Jawab:

f(x) = x⁵ + 5x × 5

  • = 5⁵ + 5(5) × 5
  • = (5.5.5.5.5) + 5(5) × 5
  • = (25.5.5.5) + 5(5) × 5
  • = (125.5.5) + 5(5) × 5
  • = (625.5) + 5(5) × 5
  • = 3.125 + (5.5) × 5
  • = 3.125 + 25 × 5
  • = 3.125 + (25×5)
  • = 3.125 + 125
  • = 3.250

Kesimpulan

Jadi, hasil dari f(x) = x⁵ + 5x × 5 adalah 3.250
