I'm taking "part 3" to mean the 3rd of the posted questions.

If $f(x)=(x^3+2x)\ln x$ , then

$f'(x)=(x^3+2x)'\ln x+(x^3+2x)(\ln x)'=(3x^2+2)\ln x+\dfrac{x^3+2x}x$

$\implies f'(x)=(3x^2+2)\ln x+x^2+2$

Then when $x=1$ , we get $f'(1)=3$ .

Answer:

$x = 5$

Step-by-step explanation:

$7x+16x-56=59$

$23x -56 = 5 9$

$2 3 x - 5 6 + 5 6 = 5 9 + 5 6$

$23x=115$

$\frac{23x}{23} = \frac{115}{23}$

$x = 5$
