I'm sure this is easy for the most of you, but i'd just like to know how i get from the first step to the other. Thanks in advance!

Format might be weird, but I'll try my best.

As a rule with limits, you can extract constants. So (x^2)/(-x * ln(3)) has the constant [-ln(3)] in the denominator
Rewrite it as (x^2)/(x) * (-1)/(ln(3))
And extract the constant to the front of the limit, and simplify the limit to x {x =\= 0} and viola.
You are left with the second step

Hope this helped.

Cancel out the x and pull out the constant.

It's just a property of limits [eqn] \lim_{ x \to a } c f(x) = c \lim_{x \to a} f(x) [/eqn] Which if you think about it makes a lot of sense. So in this problem [eqn] \lim_{x \to 0^{+}} - \frac { x^2 } { x \ln (3) } = - \frac { 1 }{ \ln(3) } \lim_{x \to 0^{+}} x [/eqn] Where the last equality is just the application of the above property and cancellation of x.

Thank you so much! while we are at this mind to help me with this anti-derivative?

(ln(2-3x^2))/-6

>>7807351
this is not how numbers work

>>7807341
just substitute x with sqrt(x) to obtain something that looks like the derivative of arcsin

This is correct. X is a factor on the top and bottom of the fraction, so it can be pulled out as X/X or 1. Then we can pull out -1/ln3 because it is not reliant on X. If it were -X^2/XlnX, it would simplify to -X/lnX and you could not pull out the -1/lnX term.

I hope that makes some sense.
