Answer 1

Penjelasan dengan langkah-langkah:

1.)

f (×) = ×!! × x4 ÷ x^2

f (8) = 8!!×x4×8^2

f (8) = (8×6×4×2)×8(4)×(8×8)

f (8) = (48×4×2)×32×64

f (8) = (192×2)×32×64

f (8) = (384)×32×64

f (8) = 384×32×64

f (8) = 12,288÷64

f (8) = 192 ✔

2.)

20 × 20 ÷ 10 ( 15 + 20 - 5 )

400 ÷ 10 ( 35 - 5 )

40 ( 35 - 5 )

40 × 35

1,200 ✔

maaf klok ada yang salah yaaa!!!!

Answer 2

Jawaban

NOMOR 1

f(8) = 8!! × 8(4) : 8²

f(8) = (8.6.4.2) × 8(4) : (8 × 8)

f(8) = (48.4.2) × 8(4) : 64

f(8) = (192.2) × 8(4) : 64

f(8) = 384 × 8(4) : 64

f(8) = 384 × (8 × 4) : 64

f(8) = 384 × 32 : 64

f(8) = 12.288 : 64

f(8) = 192

NOMOR 2

20 × 20 : 10(15 + 20 - 5) = 20 × 20 : 10(35 - 5)

20 × 20 : 10(15 + 20 - 5) = 20 × 20 : 10(30)

20 × 20 : 10(15 + 20 - 5) = 400 : 10(30)

20 × 20 : 10(15 + 20 - 5) = 400 : 10 × 30

20 × 20 : 10(15 + 20 - 5) = 40 × 30

20 × 20 : 10(15 + 20 - 5) = 1.200
