Q

f(x) = x!! × x² ÷ x(8)
f(7) =.....

hai ​

f(x) = x!! × x² ÷ x(8)

f(7) = 7!! × 7² ÷ 7(8)

f(7) = (7.5.3) × (7.7) ÷ (7.8)

f(7) = 105 × 49 ÷ 56

f(7) = 5.145 ÷ 56

f(7) = 91,875

Jawaban:

92

Penjelasan dengan langkah-langkah:

f(x) = x!! × x² ÷ x(8)

f(7) = 7!! × 7² ÷ 7(8)

= (7 × 5 × 3 × 1) × (7 × 7) ÷ 56

= 105 × 49 ÷ 56

= 5.145 ÷ 56

= 91,8

≈ 92
