Answer 1

1. 10 + 7! = 5.050
2. 6! + 7⁶ = 118.369

Penyelesaian

• Nomor 1 (No. 1):

10 + 7!

= 10 + (7 × 6 × 5 × 4 × 3 × 2 × 1)

= 10 + (42 × 5 × 4 × 3 × 2 × 1)

= 10 + (210 × 4 × 3 × 2 × 1)

= 10 + (840 × 3 × 2 × 1)

= 10 + (2.520 × 2 × 1)

= 10 + (5.040 × 1)

= 10 + 5.040

= 5.050

Jadi, hasil dari 10 + 7! adalah 5.050.

• Nomor 2 (No. 2):

6! + 7⁶

= (6 × 5 × 4 × 3 × 2 × 1) + (7 × 7 × 7 × 7 × 7 × 7)

= (30 × 4 × 3 × 2 × 1) + (49 × 7 × 7 × 7 × 7)

= (120 × 3 × 2 × 1) + (343 × 7 × 7 × 7)

= (360 × 2 × 1) + (2.401 × 7 × 7)

= (720 × 1) + (16.807 × 7)

= 720 + 117.649

= 118.369

Jadi, hasil dari 6! + 7⁶ adalah 118.369.

Answer 2

1.) 10+7!=5.050

Cara:

7!=( 7 × 6 × 5 × 4 × 3 × 2 × 1 )

=( 42 × 20 × 6 ) × 1

=( 840 × 6 ) × 1

=5.040

Jadi jika 10 + 5.040 = 5.050

2.) 6!+7⁶=118.369

Cara:

6!=( 6 × 5 × 4 × 3 × 2 × 1 )

=( 30 × 12 × 2 )

=( 360 × 2 )

= 720

7⁶=( 7 × 7 × 7 × 7 × 7 × 7 )

=( 49 × 49 × 49 )

=( 2.401 ×49 )

= 117.649

Jadi jika 720 + 117.649 = 118.369
