1-When you have a the logarithm given in the problem above, you can solve it by using the correct properties for logaritms.
2- The students could solve it as below:
<span>log4(2x-12)=3
4^[</span> log4(2x-12)]=4^3
3- By definition a^log(x)=x, therefore,
2x-12=4^3
2x-12=64
4- Now, the students can solve for x:
x=38
The first step is incorrect, because the term on the right member must be 4^3.
So distance=rate x time and if we rearrange this to find the time we get time=distance/rate. Now we can just plug in the numbers.
3.54*10^7/3*10^8=time(seconds)
To solve this we can just divide the parts of the scientific notation separately.
3.54/3=1.18
10^7/10^8=1/10
Now we just multiply our answers together because we separated them before we divided.
1.18*1/10=.118
So the answer is .118 seconds
Answer:
B) 24
Step-by-step explanation:
because we just know.
