Answer:
Step-by-step explanation:
Given
Required
Solve using differentials
In differentiation:
Express 126 as 125 + 1;
i.e.
So, we have:
To calculate f(125), we have:
So:
Also:
Rewrite as:
Differentiate
Using law of indices, we have:
So:
So, we have:
We need to know wat it looks like
x/2 < -1
Solve for x by multiplying both sides by 2:
X <-2
The solution for X is any number less than -2
Four solutions can be:
-3, -4, -5, -6
Answer: 1/3
