Jawaban:

$\tt \: f(x) = {x}^{3} \times 4x \div x!!$

$\tt \: f(8) = 42.6$

Penyelesaian :

$\sf \: f(x) = {x}^{3} \times 4x \div x!!$

$\sf \: f(8) = {8}^{3} \times 4(8) \div 8!!$

$\sf \: f(8) = (8 \times 8 \times 8) \times (4 \times 8) \div (8 \times 6 \times 4 \times 2)$

$\sf \: f(8) = 512 \times 32 \div 384$

$\sf \: f(8) = (512 \times 32) \div 384$

$\sf \: f(8) = 16.384 \div 384$

$\sf \: f(8) = 42.6$

Hasil koma = 42,6
Jika hasilnya dibulatkan adalah = 43
