Answer 1

☞ pembahasan :

13!!

= {( 13 × 11 ) × ( 9 × 7 )} × {( 5 × 3 ) × 1 }

= ( 143 × 63 ) × ( 15 × 1 )

= 9.009 × 15

= 135.135

3! + 7! × 5!

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

= 6 + {( 42 × 20 ) × ( 6 × 1 )} × {( 20 × 6 ) × 1 )}

= 6 + {( 840 × 6 ) × ( 120 × 1 )}

= 6 + ( 5.040 × 120 )

= 6 + 604.800

= 604.806
