3! + 5! =
= 3 x 2 x 1 + 5 x 4 x 3 x 2 x 1
= 6 x 1 + 5 x 4 x 3 x 2 x 1
= 6 + 5 x 4 x 3 x 2 x 1
= 6 + 20 x 3 x 2 x 1
= 6 + 60 x 2 x 1
= 6 + 120 x 1
= 6 + 120
= 126

3! =
= 3 x 2 x 1
= 6 x 1
= 6
______________________
5! =
= 5 x 4 x 3 x 2 x 1
= 20 x 3 x 2 x 1
= 60 x 2 x 1
= 120 x 1
= 120

Jawaban:
3! + 5! =
= ( 3 × 2 × 1 ) + ( 5 × 4 × 3 × 2 × 1 )
= ( 6 × 1 ) + ( 20 × 3 × 2 × 1 )
= 6 + ( 60 × 2 × 1 )
= 6 + ( 120 × 1 )
= 6 + 120
= 126
3! =
= 3 × 2 × 1
= 6 × 1
= 6
5! =
= 5 × 4 × 3 × 2 × 1
= 20 × 3 × 2 × 1
= 60 × 2 × 1
= 120 × 1
= 120
7! =
= 7 × 6 × 5 × 4 × 3 × 2 × 1
= 42 × 5 × 4 × 3 × 2 × 1
= 210 × 4 × 3 × 2 × 1
= 840 × 3 × 2 × 1
= 2.520 × 2 × 1
= 5.040 × 1
= 5.040
