B) ![log_{8}(9)](https://tex.z-dn.net/?f=log_%7B8%7D%289%29)
C) ![log_{9}(25)](https://tex.z-dn.net/?f=log_%7B9%7D%2825%29)
Step-by-step explanation:
Hello! I am going to walk you through how some simple rules regarding logs!
For A, we will use the 'AM' rule! When adding logs of the same base (in this case 5), you multiply the two answers (3 and 4)!
3 · 4 = 12, giving us
!
For B, we will use the 'SD' rule! When subtracting logs of the same base (in this case 8), you divide the two answers (9 and 5)!
9/5 =
; simplify! (9/5) x 5 = 9, giving us
!
For C, we will use the 'MS' rule! When multiplying a number times a logarithm, you can get the same argument by removing the coefficient (2) and squaring the log's answer (5)!
, giving us
!
I hope that this helps!

Answer:
2.8¢, true
Step-by-step explanation:
The value of copper in a penny is reportedly about ...
(0.95 × 3.11 g)×(1 oz)/(28.35 g)×($0.27/oz) ≈ $0.028
Today, the value of the copper in a pre-1982 penny is about 2.8¢, more than double the value of the penny as legal tender.
The claim is true.
Answer:
{y,x} = {5/3,1/2}
Step-by-step explanation:
Sum would be 0 because the sum of additional inverses is always zero and the h would be on -1.4
Answer:
x=10 n=18.5 s=6
Step-by-step explanation:
4x-10=30
Add 10 to both sides
4x-10+10=30+10
4x=40
Divide by 4 on both sides
(4x)/4=40/4
x=10
2n-7=30
Add 7 to both sides
2n-7+7=30+7
2n=37
Divide by 2 on both sides
(2n)/2=37/2
n=18.5
(s/3)+2=4
Subtract 2 from both sides
(s/3)+2-2=4-2
(s/3)=2
Multiply by 3 on both sides
3s/3=2*3
s=6
