f(x) = 7x² × 7x² + 4!
f(9) = 7(9)² × 7(9)² + 4!
f(9) = 7(9 × 9) × 7(9)² + 4!
f(9) = 7(81) × 7(9)² + 4!
f(9) = (7 × 81) × 7(9)² + 4!
f(9) = 567 × 7(9)² + 4!
f(9) = 567 × 7(9 × 9) + 4!
f(9) = 567 × 7(81) + 4!
f(9) = 567 × (7 × 81) + 4!
f(9) = 568 × 567 + 4!
f(9) = 568 × 568 + (4 × 3) × 2 × 1)
f(9) = 568 × 568 + (12 × 2) × 1)
f(9) = 568 × 568 + (24 × 1)
f(9) = (567 × 567) + 24
f(9) = 321.489 + 24
f(9) = 321.513
Kesimpulan hasil dari f(9) adalah : 321.513
f(x) = 7x² × 7x² + 4!
f(9) = 7 ( 9² ) × 7 ( 9² ) + 4!
f(9) = 7 ( 9 × 9 ) × 7 ( 9 × 9 ) + ( 4 × 3 × 2 × 1)
f(9) = 7 ( 81 ) × 7 ( 81 ) + ( 12 × 2 )
f(9) = 567 × 567 + 24
f(9) = 321.489 + 24
f(9) = 321.513
