〰️〰️〰️〰️〰️〰️〰️〰️〰️〰️〰️〰️〰️​ ✏ jawaban :

➠1! + 2! = 3

➠ 3! + 4! = 30

➠ 5! + 6! = 840

➠ 7! + 8! = 45.360

➠ 9! + 10! = 3.991.680

✏ Cara pengerjaan soal nomor 1 :

➠ 1! = ( 1 x 1 )
= ( 1 )

➠ 2! = ( 2 x 1 )
= ( 2 )

➠ 1! + 2! = ( 1 + 2 )
= ( 3 )

✏ Cara pengerjaan soal nomor 2 :

➠ 3! = ( 3 x 2 x 1 )
= ( 6 x 1 )
= ( 6 )

➠ 4! = ( 4 x 3 x 2 x 1 )
= ( 12 x 2 x 1 )
= ( 24 x 1 )
= ( 24 )

➠ 3! + 4! = ( 6 + 24 )
= ( 30 )

✏ Cara pengerjaan soal nomor 3 :

➠ 5! = ( 5 x 4 x 3 x 2 x 1 )
= ( 20 x 3 x 2 x 1 )
= ( 60 x 2 x 1 )
= ( 120 x 1 )
= ( 120 )

➠ 6! = ( 6 x 5 x 4 x 3 x 2 x 1 )
= ( 30 x 4 x 3 x 2 x 1 )
= ( 120 x 3 x 2 x 1 )
= ( 360 x 2 x 1 )
= ( 720 x 1 )
= ( 720 )

➠ 5! + 6! = ( 120 + 720 )
= ( 840 )

✏ Cara pengerjaan soal nomor 4 :

➠ 7! = ( 7 x 6 x 5 x 4 x 3 x 2 x 1 )
= ( 42 x 5 x 4 x 3 x 2 x 1 )
= ( 210 x 4 x 3 x 2 x 1 )
= ( 840 x 3 x 2 x 1 )
= ( 2.520 x 2 x 1 )
= ( 5.040 x 1 )
= ( 5.040 )

➠ 8! = ( 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 )
= ( 56 x 6 x 5 x 4 x 3 x 2 x 1 )
= ( 336 x 5 x 4 x 3 x 2 x 1 )
= ( 1.680 x 4 x 3 x 2 x 1 )
= ( 6.720 x 3 x 2 x 1 )
= ( 20.160 x 2 x 1 )
= ( 40.320 x 1 )
= ( 40.320 )

➠ 7! + 8! = ( 5.040 + 40.320 )
= ( 45.360 )

✏ Cara pengerjaan soal nomor 5 :

➠ 9! = ( 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 )
= ( 72 x 7 x 6 x 5 x 4 x 3 x 2 x 1 )
= ( 504 x 6 x 5 x 4 x 3 x 2 x 1 )
= ( 3.024 x 5 x 4 x 3 x 2 x 1 )
= ( 15.120 x 4 x 3 x 2 x 1 )
= ( 60.480 x 3 x 2 x 1 )
= ( 181.440 x 2 x 1 )
= ( 362.880 x 1 )
= ( 362.880 )

➠ 10! = ( 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 )
= ( 90 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 )
= ( 720 x 7 x 6 x 5 x 4 x 3 x 2 x 1 )
= ( 5.040 x 6 x 5 x 4 x 3 x 2 x 1 )
