SOAL Q.

5! × 6!

= (5.4.3.2.1) × (6.5.4.3.2.1)

= (20.3.2.1) × (30.4.3.2.1)

= (60.2.1) × (120.3.2.1)

= (120.1) × (360.2.1)

= 120 × (720.1)

= 120 × 720

= 86.400

I Hope This Help!

5! × 6!

= ( 5 × 4 × 3 × 2 × 1 ) × 6!

= ( 20 × 3 × 2 × 1 ) × 6!

= ( 20 × 6 × 1 ) × 6!

= ( 120 × 1 ) × 6!

= 120 × 6!

= 120 × ( 6 × 5 × 4 × 3 × 2 × 1 )

= 120 × ( 30 × 4 × 3 × 2 × 1 )

= 120 × ( 30 × 12 × 2 × 1 )

= 120 × ( 30 × 12 × 2 )

= 120 × ( 360 × 2 )

= 120 × 720

$\boxed{ = 86.400 }$
