When working with logarithms, remember that a subtraction sign means you can divide.
log(400) - log(4) can be turned into log(400/4), which is further simplified to log(100).

Step-by-step explanation:
Its the identity property
Answer:
A. 
Step-by-step explanation:
We have been given that f be a differentiable function such that
,
,
, and
. The function g is differentiable and
for all x.
We know that when one function is inverse of other function, so:

Upon taking derivative of both sides of our equation, we will get:


Plugging
into our equation, we will get:

Since
, then
.

Since we have been given that
, so we will get:


Therefore,
and option A is the correct choice.

Step-by-step explanation:
7 + 3 = 10
+ 679 - 2056 = -1377
- 398 + 1 = -397
-23 - 237 = 260
2 - 6 = -4
-2 × 3 × -4 = 24
absolute value of -36 = 36
6 + 4 = 10
- 5928 - 965 = -6893
215 × 212 + 212 × 314 = 112148
(15 + 5) ÷ (15 + 5) = 20 ÷ 20 = 1
-457 + 1 = -456
- 218 -1 = -219
