QUIZ

f(s) = 2x² + 3x³
f(3) =

f(m) = 5x² + 7x²
f(6) =

f(3) × f(6) = (Gunakan Perkalian Bersusun Kebawah)

Harus rapih!

​

Answer 1

f(s) = 2x² + 3x³

f(3) = 2(3)² + 3(3)³

f(3) = 2(9) + 3(27)

f(3) = 18 + 81

f(3) = 99

f(m) = 5x² + 7x²

f(6) = 5(6)² + 7(6)²

f(6) = 5(36) + 7(36)

f(6) = 180 + 252

f(6) = 432

Ditanya

f(3) × f(6)

= 99 × 432

= 42.768

Answer 2

Jawaban:

Penyelesaian :

=> f(3)

• f(s) = 2x² + 3x³

• f(3) = 2(3)² + 3(3)³

• f(3) = 2(3²) + 3(3³)

• f(3) = 2( 3 × 3 ) + 3( 3 × 3 × 3 )

• f(3) = 2(9) + 3( 9 × 3 )

• f(3) = ( 2 × 9 ) + 3(27)

• f(3) = 18 + ( 3 × 27 )

• f(3) = 18 + 81

• f(3) = 99

=> f(6)

• f(m) = 5x² + 7x²

• f(6) = 5(6)² + 7(6)²

• f(6) = 5(6²) + 7(6²)

• f(6) = 5( 6 × 6 ) + 7( 6 × 6 )

• f(6) = 5(36) + 7(36)

• f(6) = ( 5 × 36 ) + ( 7 × 36 )

• f(6) = 180 + 252

• f(6) = 432

=> f(3) × f(6)

• = 99 × 432

• = 42.768
