Jawaban:
8! x 9!
= ( 8 x 7 x 6 x 5 x 4 x 3 x 2 ) x ( 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 )
= 40.320 x 362.880
= 14.631.321.600
3! + 2!
= ( 3 x 2 ) + ( 2 x 1 )
= 6 + 2
= 8
Jawaban:
1.) 8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 40.320
9! = 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 =362.880
40.320 × 362.880 = 14631321600
2.) 3! = 3 × 2 × 1 = 6
2! = 2 × 1 = 2
6 + 2 = 8
