Penjelasan dengan langkah-langkah:
f(x) = x⁴ + x × 10³
f(10) = 10⁴ + 10 × 10³
= ( 10 × 10 × 10 × 10 ) + 10 × 10³
= ( 100 × 100 ) + 10 × ( 10 × 10 × 10 )
= 10.000 + 10 × ( 100 × 10 )
= 10.000 + 10 × 1.000
= 10.000 + 10.000
= 20.000
Maka hasilnya adalah 20.000 ✅
5! + 5!
= ( 5 × 4 × 3 × 2 × 1 ) + ( 5 × 4 × 3 × 2 × 1 )
= ( 20 × 6 × 1 ) + ( 20 × 6 × 1 )
= 120 + 120
= 240
Maka hasil dari 5! + 5! adalah 240 ✅

Soal 1
f(x) = x⁴ + x × 10³
f(10) = 10⁴ + 10 × 10³
f(10) = (10 × 10 × 10 × 10) + 10 × (10 × 10 × 10)
f(10) = (100 × 10 × 10) + 10 × (10 × 10 × 10)
f(10) = (1.000 × 10) + 10 × (10 × 10 × 10)
f(10) = 10.000 + 10 × (10 × 10 × 10)
f(10) = 10.000 + 10 × (100 × 10)
f(10) = 10.000 + 10 × 1.000
f(10) = 10.000 + 10.000
f(10) = 20.000

Soal 2
→ 5❗ + 5❗
→ (5 × 4 × 3 × 2 × 1) + (5 × 4 × 3 × 2 × 1)
→ (20 × 3 × 2 × 1) + (5 × 4 × 3 × 2 × 1)
→ (60 × 2 × 1) + (5 × 4 × 3 × 2 × 1)
→ (120 × 1) + (5 × 4 × 3 × 2 × 1)
→ 120 + (5 × 4 × 3 × 2 × 1)
→ 120 + (20 × 3 × 2 × 1)
→ 120 + (60 × 2 × 1)
→ 120 + (120 × 1)
→ 120 + 120
→ 240
