    \bf\Huge\red{\mid{\overline{\underline{ ANSWER }}}\mid }

    ➡️(i) Consider 8!

    ➡️We know that 8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

    ➡️= 40320

    ➡️(ii) Consider 4!-3!

    ➡️4!-3! = (4 × 3!) – 3!

    ➡️Above equation can be written as

    ➡️= 3! (4-1)

    ➡️= 3 × 2 × 1 × 3

    ➡️= 18
