f(x) = 2x² + 100 ÷ 10x
Maka, Nilai f(5)
f(5) = 2(5)² + 100 ÷ 10(5)
f(5) = 2(5 × 5) + 100 ÷ (10 × 5)
f(5) = 2(25) + 100 ÷ 50
f(5) = (2 × 25) + 100 ÷ 50
f(5) = 50 + 100 ÷ 50
f(5) = 50 + (100 ÷ 50)
f(5) = 50 + 2
f(5) = 52
f(x) = 2x² + 100 : 10x
f(5) = 2(5)² + 100 : 10(5)
f(5) = 2(25) + 100 : 10(5)
f(5) = ( 2 × 25 ) + 100 : ( 10 × 5 )
f(5) = 50 + 100 : 50
f(5) = 50 + 2
f(5) = 52
