Answer 1

8!! + 7!! + 6 × 10²

= ( 8.6.4.2 ) + ( 7.5.3.1 ) + 6 × 100

= 384 + 105 + 600

= 384 + 705

= 1.089

8 + 5 × 10

= 58

Answer 2

→ 8!! + 7x!! + 6 × 10²

8!!
= 8 × 6 × 4 × 2
= 48 × 4 × 2
= 192 × 2
= 384

7!!
= ( 7 × 5 × 3 × 1 )
= ( 35 × 3 × 1 )
= ( 105 × 1 )
= 105


8!! + 7!! + 6 × 10²
= ( 8 × 6 × 4 × 2 ) + ( 7 × 5 × 3 × 1 ) + 6 × ( 10 × 10 )
= ( 8 × 6 × 4 × 2 ) + ( 7 × 5 × 3 × 1 ) + 6 × 100
= 384 + 105 + 600
= 384 + 705
= 1.089

→ 8 + 5 × 10
= 8 + 50
= 58
