Answer:
Just B and C
Step-by-step explanation:
Reduce this to the lowest amount possible.
log(3abc/6a^2b) = 2
=================
log(c/2a) = 2
c/2a = 10^2
c = 2a * 100
c = 200a
This one is also correct.
=================
The rest are just incorrect.
There is only 1 answer that works and that is B.
C is close, but it is not correct.
D is backwards. B is the right way and D is the upside down of B.
E and F are just not the way to handle logs. Subtracting logs means division, not multiplication and not 1 log.
=================
They would use 8 signs because one mile in this case is broken up into quarters so in a mile it would have 1/4 1/2 3/4 and 1 mile times that by two because they are placing signs for 2 miles so 4+4= 8

x^(1/2) means that you are taking the square root of some number. You can use this symbol on your calculator √ . So √16 is 4. The 1/2 in this case is a power.
Put it in your calculator this way.
√
16
=
It should come up as 4.
So the answer is A.
