The answer is 20 because there are 5 parts of we divide the question by 4 and then if we minus 4 from 20 then it would be 16
Given:

To find:
The value of
.
Solution:
We have,

It can be written as

Using property of log, we get
![[\because \log_aa^x=x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog_aa%5Ex%3Dx%5D)
Now, differentiate both sides with respect to x.

![[\because \dfrac{d}{dx}(Constant)=0]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cdfrac%7Bd%7D%7Bdx%7D%28Constant%29%3D0%5D)
Therefore, the value of
is 0.
Answer:
2
Step-by-step explanation:
