Question

Hi. I need help whit this question (see image). Please show workings.​

Answer 1

Answer:

54x² - 10x

Step-by-step explanation:

differentiate each term using the power rule

$\frac{d}{dx}$ (a$x^{n}$ ) = na$x^{n-1}$, then

$\frac{d}{dx}$(18x³ - 5x² + 6)

= 3.18$x^{3-1}$ - 2.5$x^{2-1}$ + 0

= 54x² - 10x

Answer 2

Answer:

54x² - 10x

Step-by-step explanation:

differentiate each term using the power rule

\frac{d}{dx}

dx

d

(ax^{n}x

n

) = nax^{n-1}x

n−1

, then

\frac{d}{dx}

dx

d

(18x³ - 5x² + 6)

= 3.18x^{3-1}x

3−1

- 2.5x^{2-1}x

2−1

+ 0

= 54x² - 10x
