1. 9! ÷ (4! – 3!) = ?Tolong bantu.​

Penjelasan dengan langkah-langkah:

9! ÷ (4! – 3!) =

9! =

= 9×8×7×6×5×4×3×2×1

= 72×7×6×5×4×3×2×1

= 504×6×5×4×3×2×1

= 3.024×5×4×3×2×1

= 15.120×4×3×2×1

= 60.480×3×2×1

= 181.440×2×1

= 362.880×1

= 362.880

4! =

= 4 × 3 × 2 × 1

= 12 × 2 × 1

= 24 × 1

= 24

3! =

= 3 × 2 × 1

= 6 × 1

= 6

9! ÷ (4! – 3!) =

= 362.880 ÷ (24 – 6)

= 362.880 ÷ 18

= 20.160

9! ÷ (4! – 3!)

=9! ÷ ((4×3×2×1) – (3×2×1)

=9! ÷ (24 – 6)

=9! ÷ (18)

=9! ÷ 18

= frac{9!}{18}

= frac{9 times 8 times 7 times 6 times 5 times 4 times 3 times 2 times 1}{18}

= frac{362.880}{18}

= frac{362.880 div 18}{18 div 18}

= frac{20.160}{1}

=20.160
