Next level (6/10)Tentukan nilai dari :8! – 7!Note : – ​

8! = (8 × 7 × 6 × 5 × 4 × 3 × 2 × 1)

8! = (56 × 6 × 5 × 4 × 3 × 2 × 1)

8! = (336 × 5 × 4 × 3 × 2 × 1)

8! = (1.680 × 4 × 3 × 2 × 1)

8! = (6.720 × 3 × 2 × 1)

8! = (20.160 × 2 × 1)

8! = 40.320

7! = ….

= (7 × 6 × 5 × 4 × 3 × 2 × 1)

= (42 × 5 × 4 × 3 × 2 × 1)

= (210 × 4 × 3 × 2 × 1)

= (840 × 3 × 2 × 1)

= (2.520 × 2 × 1)

= (5.040 × 1)

= 5.040

8! – 7! = …

= 40.320 – 5.040

= 35.280

Penyelesaian:

8!-7!

=8×7×6×5×4×3×2×1-7×6×5×4×3×2×1

=40.320-5.040

=35.280
