2. 9! + 6 =

3. 5! + 7 =

Jawaban:

1. 5.046

2. 362.886

3. 127

Penjelasan dengan langkah-langkah:

1. 7! = 7 x 6 x 5 x 4 x 3 x 2 x 1

= 42 x 5 x 4 x 3 x 2 x 1

= 210 x 4 x 3 x 2 x 1

= 810 x 3 x 2 x 1

= 2.520 x 2 x 1

= 5.040 x 1

= 5.040

------------ (+)

5.046

2. 9! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

= 72 x 7 x 6 x 5 x 4 x 3 x 2 x 1

= 504 x 6 x 5 x 4 x 3 x 2 x 1

= 3.024 x 5 x 4 x 3 x 2 x 1

= 15.120 x 4 x 3 x 2 x 1

= 60.480 x 3 x 2 x 1

= 181.440 x 2 x 1

= 362.880 x 1

= 362.880

3. 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

7

-------- (+)
