Answer 1

f(3) = 7x³ × 5x³ + 7x

f(3) = 7(3)³ × 5(3)³ + 7(3)

f(3) = 7(27) × 5(27) + 21

f(3) = 189 × 135 + 21

f(3) = 25.515 + 21

f(3) = 25.536

f(x) = 7x³ × 5x³ + 7x

f(3) = ...

• f(3) = 7(3³) × 5(3³) + 7(3)

• f(3) = 7(3 × 3 × 3) × 5(3 × 3 × 3) + 7(3)

• f(3) = 7(9 × 3) × 5(3 × 3 × 3) + 7(3)

• f(3) = 7(27) × 5(3 × 3 ×3) + 7(3)

• f(3) = 7(27) × 5(9 × 3) + 7(3)

• f(3) = 7(27) × 5(27) + 7(3)

• f(3) = 189 × 5(27) + 7(3)

• f(3) = 189 × 135 + 7(3)

• f(3) = 189 × 135 + 21

• f(3) = 25.515 + 21

• f(3) = 25.536 ✔
