9! + √169 - 7! ÷ 100 × 4/12 = ... ?
cara paling lengkap BA, yg jwb di follow
9! + √169 - 7! : 100 x 4/12
_________________________
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
√169 = ?
√169
= √13²
= 13
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
362.880 + 13 - 5.040 : 100 x 4/12
362.880 + 13 - 50,4 x 4/12
362.880 + 13 - 201,6/12
362.880 + 13 - 16,8
362.893 - 16,8
= 362.876,2
Jawaban:
362.876,6
Penjelasan dengan langkah-langkah:
9! + √169 - 7! ÷ 100 × 4/12 =
= 9! + √169 - 7! ÷ 100 × 4/12
= 362.880 + 13 - 5.040 ÷ 100 × 4/12
= 362.880 + 13 - 50,4 × 4/12
= 362.880 + 13 - 201,6/12
= 362.880 + 13 - 16,8
= 362.893 - 16,8
= 362.876,6
