Diketahui
f(a) = 5a³ × 2a + 1a²
f(7) = ?
f(7) = 5(7)³ × 2(7) + 1(7)²
f(7) = 5(7³) × 2(7) + 1(7²)
f(7) = 5( 7 × 7 × 7 ) × 2(7) + 1(7²)
f(7) = 5( 49 × 7 ) × 2(7) + 1(7²)
f(7) = 5(343) × 2(7) + 1(7²)
f(7) = ( 5 × 343 ) × 2(7) + 1(7²)
f(7) = 1.715 × ( 2 × 7 ) + 1(7²)
f(7) = 1.715 × 14 + 1( 7 × 7 )
f(7) = 1.715 × 14 + 1(49)
f(7) = 1.715 × 14 + ( 1 × 49 )
f(7) = 1.715 × 14 + 49
f(7) = ( 1.715 × 14 ) + 49
f(7) = 24.010 + 49
Jadi, hasil nya adalah 24.059
