Answer:

Step-by-step explanation:

(f.g)(x) = (x² - 2x + 3) (x³ - 4)

= x²* (x³ - 4) - 2x* (x³ - 4) + 3 * (x³ - 4)

= x²*x³ - x²*4 - 2x*x³ - 2x*(-4) + 3*x³ - 3 * 4

= x⁵ - 4x² - 2x⁴ + 8x + 3x³ - 12

= x⁵ - 2x⁴ + 3x³ - 4x² + 8x - 12

Differentiate y= ln (6 – 3x)^4

dsp73

Step-by-step explanation:

$\frac{dy}{dx} = \frac{1}{ {(6 - 3x)}^{4} } \times {4(6 - 3x)}^{3} ( - 3) \\ = \frac{ - 12 {(6 - 3x)}^{3} }{ {(6 - 3x)}^{4} } \\ = - \frac{12}{6 - 3x}$

I hope I'm correct. I've never learnt differentiation for log and exponents before
