f(8) = ...
f(x) = 7!! × x² + 24 - 5³
f(8) = (7 × 5) × 3 × 1) × 8² + 24 - 5³
f(8) = (35 × 3) × 1) × 8² + 24 - 5³
f(8) = (105 × 1) × 8² + 24 - 5³
f(8) = 105 × 8² + 24 - 5³
f(8) = 105 × (8 × 8) + 24 - 5³
f(8) = 105 × 64 + 24 - 5³
f(8) = 105 × 64 + 24 - (5 × 5) × 5)
f(8) = 105 × 64 + 24 - (25 × 5)
f(8) = (105 × 64) + 24 - 125
f(8) = (6.720 + 24) - 125
f(8) = 6.744 - 125
f(8) = 6.619
Kesimpulan hasilnya adalah : 6.619
