Answer:
14. 5log3(x) -2log3(y)
18. ln(x+1) -2ln(x)
Step-by-step explanation:
The relevant rules of logarithms are ...
log(ab) = log(a) +log(b)
log(a^b) = b·log(a)
___
14. Applying the first rule gives ...
log3(x^5) +log3(y^-2)
Applying the second rule gives ...
5·log3(x) -2·log3(y)
___
18. The log of a sum cannot be simplified. We can make this be a simpler expression so that the log of it will be fairly simple.
ln(1/x +1/x^2) = ln(x/x^2 +1/x^2) = ln((x+1)/x^2)
Now, we can apply rule 1 to get ...
ln(x+1) +ln(1/x^2)
and applying rule 2 gives ...
ln(x+1) -2ln(x)

Answer:
$7500
Step-by-step explanation:
We have been given the formula to use but we will have to be able to recognize what each of the letters in the formula represent
A=P(1+r)t
A stands for the interest
P stands for principal
r stands for the rate
t stands for the time
So from the question we can deduce that we are to find the value A
P=$300
r=4%
t=5years
A=?
A=300(1+4)5
Using the BODMAS principle by solving the bracket first
A=300(5)5
A=300(25)
A=7500
Therefore the interest is $7500
Answer: $30
Step-by-step explanation:
I=PRT
I= (300)(0.05)(2)
I= 15(2)
I= 30
