Answer 1

Jawaban:

• Diketahui :

f(z) = 4z² × 3z³ + 4z - 5z

• Ditanya :

f(7) = ...

• Jawab :

f(z) = 4z² × 3z³ + 4z - 5z

f(7) = 4(7²) × 3(7³) + 4(7) - 5(7)

f(7) = 4(7 × 7) × 3(7³) + 4(7) - 5(7)

f(7) = 4(49) × 3(7³) + 4(7) - 5(7)

f(7) = ( 49 + 49 + 49 + 49 ) × 3(7³) + 4(7) - 5(7)

f(7) = ( 98 + 49 + 49 ) × 3(7³) + 4(7) - 5(7)

f(7) = ( 147 + 49 ) × 3(7³) + 4(7) - 5(7)

f(7) = 196 × 3(7 × 7 × 7) + 4(7) - 5(7)

f(7) = 196 × 3(49 × 7) + 4(7) - 5(7)

f(7) = 196 × 3(343) + 4(7) - 5(7)

f(7) = 196 × ( 343 + 343 + 343 ) + 4(7) - 5(7)

f(7) = 196 × ( 686 + 343 ) + 4(7) - 5(7)

f(7) = 196 × 1.029 + 4(7) - 5(7)

f(7) = 201.684 + 4(7) - 5(7)

f(7) = 201.684 + ( 7 + 7 + 7 + 7 ) - 5(7)

f(7) = 201.684 + ( 14 + 7 + 7 ) - 5(7)

f(7) = 201.684 + ( 21 + 7 ) - 5(7)

f(7) = 201.684 + 28 - 5(7)

f(7) = 201.684 + 28 - ( 7 + 7 + 7 + 7 + 7 )

f(7) = 201.684 + 28 - ( 14 + 7 + 7 + 7 )

f(7) = 201.684 + 28 - ( 21 + 7 + 7 )

f(7) = 201.684 + 28 - ( 28 + 7 )

f(7) = 201.684 + 28 - 35

f(7) = 201.712 - 35

f(7) =

Answer 2

f(z) = 4z² × 3z³ + 4z - 5z

f(7) = 4(7)² × 3(7)³ + 4(7) - 5(7)

f(7) = 4(7 × 7) × 3(7 × 7 × 7) + 28 - 35

f(7) = 4(49) × 3(343) + 28 - 35

f(7) = 196 × 1.029 + 28 - 35

f(7) = 201.684 + 28 - 35

f(7) = 201.712 - 35

f(7) = 201.677
