[tex] \sf \: f(g) = {g}^{2} + 5(g) \times g(g)^{2} \\ \sf \: f(9) = .......... \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]
f(g) = g² + 5(g) × g(g)²
f(9) = 9² + 5(9) × 9(9)²
f(9) = (9 × 9) + (5 × 9) × 9(9 × 9)
f(9) = 81 + 45 × 9(81)
f(9) = 81 + 45 × (9 × 81)
f(9) = 81 + 45 × 729
f(9) = 81 + 32.805
f(9) = 32.886
Jawaban
f(9) = 9² + 5(9) × 9(9)²
f(9) = (9 × 9) + (5 × 9) × (9 × (9 × 9))
f(9) = 81 + 45 × (9 × 81)
f(9) = 81 + 45 × 729
f(9) = 81 + 32.805
f(9) = 32.886
