Penjelasan dengan langkah-langkah:

$f(x) = 5x \times x! \\ f(7) = 5(7) \times (7.6.5.4.3.2) \\ f(7) = 35 \times (42.5.4.3.2) \\ f(7) = 35 \times (210.4.3.2) \\ f(7) = 35 \times (840.3.2) \\ f(7) = 35 \times (2.520.2) \\ f(7) = 35 \times 5.040 \\ f(7) = { \boxed{ \red{176.400}}}$

Jawaban:

F(x) = 5x × x!

F(7) = 5(7) × 5!

= (5 × 7) × (7 × 6 × 5 × 4 × 3 × 2 × 1)

= 35 × (42 × 20 × 6)

= 35 × (840 × 6)

= 35 × 5.040

= 176.400
