f(x) = 5x² × x!!
f(10) = 5(10)² × 10!!
f(10) = 5( 10 × 10 ) × ( 10 × 8 × 6 × 4 × 2 )
f(10) = 5(100) × ( 80 × 6 × 4 × 2 )
f(10) = ( 5 × 100 ) × ( 480 × 4 × 2 )
f(10) = 500 × ( 1.920 × 2 )
f(10) = 500 × 3.840
f(10) = 1.920.000
Penyelesaian ☁️
f(x) = 5x² × x!!
f(10) = 5×10x² × 10!!
f(10) = 5(10 × 10) × (10 × 8 × 6 × 4×2)
f(10) = ( 5×100) × (80 × 6 × 4 × 2)
f(10) = (5 × 100) × ( 480 × 4 × 2)
f(10) = 500 × (1.920 × 2)
f(10) = ( 500 × 3.840 )
f(10) = 1.920.000 ✅
