Q.

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
