Answer:
D
Step-by-step explanation:
You need to get the x out of the position in which is currently sitting, which is exponential. The only way to get an exponent out from that position is to take the log of both sides. The power rule of logs allows us to move the exponent down in front of the log. Like this:
7x - 2 log (125)=log(150)
Now you want to divide both sides by log(125) to get the 7x - 2 all by itself:
Do that on your calculator and you'll get this:
7x - 2 = 1.037760918
Add 2 to both sides to get
7x = 3.037760918
then divide both sides by 7:
x = .4339 which rounds to .4340

Step-by-step explanation:
Here is the corrected question and options:
Option 1:
Option 2:
Option 3:
Option 4:
Solution:
Lets write each of the above given numbers in a simplified form:
Simplify this by converting it into a decimal form:
This becomes:
(3*7+1) / 3 = (21 + 1) / 3 = 22/3 = 7.333333
So
= 7.3
Simplify this by converting it into a decimal form:
This becomes:
221/30 = 7.3666666667
So,
= 7.367
This number comes with a bar sign on .36 which means that the number has a non terminating repeating decimal expansion as 7.3636363636...
So after rounding it off this becomes:
7.36
Simplify this by converting it into a decimal form:
The value of e = 2.718
This becomes:
3.16
= 3.16 (√5.436)
= 3.16 * 2.331523
= 7.3679949818
= 7.368
So
= 7.368
7.367995
Now we get the numbers in decimal form:
= 7.333333 = 7.3
= 7.3666666667 = 7.367
7.36 = 7.3636363636
= 7.3679949818 = 7.368
Now lets order the numbers from greatest to least:
7.36
So the correct option is:
Option 4
