Differentiate the following equation
Bingel [31]

Answer:

\frac{dy}{dx} = \frac{4}{1-x}

Step-by-step explanation:

    y = 3 - 4ln(1 - x)

⇒ \frac{dy}{dx} =3\frac{d}{dx} -4ln(1-x)\frac{d}{dx}

⇒ \frac{dy}{dx} =0 -4ln(1-x)\frac{d}{dx}

⇒ \frac{dy}{dx} =0 -4(\frac{1}{1-x})\times-1

⇒ \frac{dy}{dx} = \frac{4}{1-x}

koban [17]
Hi there!

-  \frac{1}{3}  + 4 +  \frac{2}{3}  =
First we rearrange the sum in order to add both of the fractions first. We can rearrange because the only thing we need to do is adding.

-  \frac{1}{3}  +  \frac{2}{3}  + 4 =
Add the fractions.
** If you don't get this, think of this story: you lack 1/3 of an apple pie and someone gives you 2/3 of pie. How much pie do you have left?
- 1 / 3 + 2 / 3 = 1 / 3 **

\frac{1}{3}  + 4 =
Finally add 4 to our found fraction.

\boxed{ 4\frac{1}{3} }
Therefore, the answer is 4 1/3.
