f(x) = x² × x! + 7³
f(3) = 3² × 3! + 7 × 7 × 7
f(3) = 3 × 3 × 3 × 2 × 1 + 49 × 7
f(3) = 9 × 6 × 1 + 343
f(3) = 9 × 6 + 343
f(3) = 54 + 343

f(x) = x² × x! + 7³
f(3) = 3² × 3! + 7³
f(3) = (3×3) × (3×2×1) + (7×7×7)
f(3) = 9 × (6×1) + (49×7)
f(3) = 9 × 6 + 343
f(3) = 54 + 343
f(3) = 397
Maaf jika salah
