9!! = ..4!² + √64 + ²log 4 = ..​

Penjelasan dengan langkah-langkah:

1)

= 9!!

= 9·7·5·3·1

= 63·15

= 945

2)

= 4!² + √64 + ²log 4

= (4·3·2·1)² + √8² + 2log 2²

= 24² + 8 + 2

= 576 + 8 + 2

= 586

Penjelasan dengan langkah-langkah:

9!!

= 9 × 7 × 5 × 3 × 1

= 63 × 5 × 3 × 1

= 315 × 3 × 1

= 945 × 1

= 945

**

4!² + √64 + ²log 4

= (4 × 3 × 2 × 1)² + √8² + ²log 2²

= 24² + 8 + (1 × 2)

= 576 + 8 + 2

= 576 + 10

= 586
