Answer 1

3! + 2! × 3! + 5! - 4!

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

= ( 6 × 1 ) + 2 × ( 6 × 1 ) + ( 20 × 3 × 2 × 1 ) - ( 12 × 2 × 1 )

= 6 + 2 × 6 + ( 60 × 2 × 1 ) - ( 24 × 1 )

= 6 + 12 + ( 120 × 1 ) - 24

= 18 + 120 - 24

= 138 - 24

= 114

( 8 + 2 )²

10²

10 × 10

= 100
