Answer 1

f(x) = 6x² × 8x² + 9x²

f(x) = (6 × 8)x⁴ + 9x²

f(x) = 48x⁴ + 9x²

f(5) = 48(5)⁴ + 9(5)²

f(5) = 48(625) + 9(25)

f(5) = 30.000 + 225

f(5) = 30.225

Answer 2

Jawaban:

f(x) = 6x² × 8x² + 9x²

f(5) = ... ?

f(x) = 6x² × 8x² + 9x²

f(5) = 6(5)² × 8(5)² + 9(5)²

f(5) = (6 × 5)² × (8 × 5)² + (9 × 5)²

f(5) = 30² × 40² + 45²

f(5) = 900 × 1.600 + 2.025

f(5) = 1.440.000 + 2.025

f(5) = 1.442.025
