$sf : f(x) = {x}^{3} times x(x) - 9(x)$
$sf : f(5) = ...$

>|||<

.Q.

Penjelasan dengan langkah-langkah:

f(x) = x^3 × x(x) – 9(x)

f(5) = 5^3 × 5(5) – 9(5)

f(5) = ( 5.5.5 ) × 25 – 18

f(5) = ( 25.5 ) × 25 – 18

f(5) = 125 × 25 – 18

f(5) = 3.125 – 18

f(5) = 3.107

Gambar Jawaban

Jawaban:

f(5) = 3170

Penjelasan dengan langkah-langkah:

f(5) = (5)³ (5)² – 9(5)

= (125) (25) – 45

= 3215 – 45

= 3170
