Q. Math
f(x) = 5x² + 7x – x³
f(³log 27) = 5x² + 7x – x³
f(3) = 5x² + 7x – x³
f(3) = 5(3)² + 7(3) – 3³
f(3) = 39
f(x) = 5x² + 7x – x³
f(³log 27) = 39
- f(x) = 5x² + 7x – x³
- f(³log27) = 5x² + 7x – x³
- f(3 log 3³ ) = 5x² + 7x – x³
- f ( 3 ) = 5x² + 7x – x³
- f(3) = 5(3²) + 7(3) – 3³
- f(3) = 5(9) + 21 – ( 3 × 3 × 3 )
- f(3) = 45 + 21 – 27
- f(3) = 66 – 27
- f(3) = 39
