f(x) = x² + x⁴ × x(x) - 76
f(5) = 5² + 5⁴ × 5(5) - 76
f(5) = (5 × 5) + 5⁴ × 5(5) - 76
f(5) = 25 + (5 × 5 × 5 × 5) × 5(5) - 76
f(5) = 25 + (25 × 25) × 5(5) - 76
f(5) = 25 + 625 × (5 × 5) - 76
f(5) = 25 + 625 × 25 - 76
f(5) = 25 + 15.625 - 76
f(5) = 15.650 - 76
f(5) = 15.574
Kesimpulan :
» f(5) = 15.574
Penjelasan dengan langkah-langkah:
[tex]f(x) = {x}^{2} + {x}^{4} \times x(x) - 76[/tex]
[tex]f(x) = {x}^{2} + {x}^{4} \times {x}^{2} - 76[/tex]
[tex]f(x) = {x}^{2} \times (1 + {x}^{4} ) - 76[/tex]
[tex]f(5) = {5}^{2} \times (1 + {5}^{4} ) - 76[/tex]
[tex]f(5) = 25 \times 626 - 76[/tex]
[tex]f(5) = 15.650 - 76[/tex]
[tex]f(5) = 15.574[/tex]
