Jawaban:

( 20 × 3 ) + 100

= 60 + 100

= 160

9!! + 3! - 4!!

= ( 9 × 7 × 5 × 3 × 1 ) + ( 3 × 2 × 1 ) - ( 4 × 2 )

= 945 + 6 - 8

= 951 - 8

= 943

Jawaban:

1. 160

2. 943

Penjelasan dengan langkah langkah:

1.

[tex]20 \times 3 + 100[/tex]

[tex] = (20 \times 3) + 100[/tex]

[tex] = 60 + 100[/tex]

[tex] = 160[/tex]

2.

9!!

[tex] = (9 \times 7) \times 5 \times 3 \times 1[/tex]

[tex] = (63 \times 5) \times 3 \times 1[/tex]

[tex] = (315 \times 3) \times 1[/tex]

[tex] = 945 \times 1[/tex]

[tex] = 945[/tex]

3!

[tex] =(3 \times 2) \times 1[/tex]

[tex] = 6 \times 1[/tex]

[tex] = 6[/tex]

4!!

[tex] = 4 \times 2[/tex]

[tex] = 8[/tex]

[tex] = 945 + 6 - 8[/tex]

[tex] = (945 + 6) - 8[/tex]

[tex] = 951 - 8[/tex]

[tex] = 943[/tex]
