Q. f(x) = 2x² + 3x³f(5) =…Special Masuk Kwartalan :D

Diketahui :

f(x) = 2x² + 3x³

$:$

Ditanya :

nilai f(5) ?

$:$

Jawab :

f(x) = 2x² + 3x³
f(5) = 2(5)² + 3(5)³
f(5) = 2(5 × 5) + 3(5 × 5 × 5)
f(5) = 2(25) + 3(25 × 5)
f(5) = 2(25) + 3(125)
f(5) = (2 × 25) + 3(125)
f(5) = 50 + (3 × 125)
f(5) = 50 + 375
f(5) = 425
