a = (0!)!)!)!)!
b = (2 + 3)!
c = 2! + 1! x 0!
maka, tentukan nilai dari
= a + b + c
Jika
a = (0!)!)!)!)! = 1
b = (2 + 3)! = 5! = 120
c = 2! + 1! x 0! = 2 + 1 × 1 = 2 + 1 = 3
_______________________
a + b + c
= 1 + 5! + 2!
= 1 + ( 5 × 4 × 3 × 2 × 1 ) + 3
= 1 + ( 20 × 3 × 2 × 1 ) + 3
= 1 + ( 60 × 2 × 1 ) + 3
= 1 + ( 120 × 1 ) + 3
= 1 + 120 + 3
= 121 + 3
= 124
a + b + c = 124
Langkah Penyelesaian
Faktorial 0, hasilnya 1. Faktorial 1 hasilnya 1
a = (0!)!)!)!)!
a = (1!)!)!)!)
a = (1!)!)!)
a = (1!)!)
a = 1!
a = 1
b = (2 + 3)!
b = 5!
b = 5 × 4 × 3 × 2 × 1
b = 20 × 3 × 2 × 1
b = 60 × 2 × 1
b = 120
c = 2! + 1! × 0!
c = 2 + 1 × 1
c = 2 + 1
c = 3
a + b + c
>> 1 + 120 + 3
>> 121 + 3
>> 124
