Answer:i think it is 5
Step-by-step explanation:
The correct expansion is the one in option b:

<h3>
How to rewrite the term?</h3>
Here we must use the logarithmic property:

Our expression in this case is:

Using the above property, we can rewrite the expression as:

From this, we conclude that the correct option is B.

Given:

To find:
The solution of the given equation.
Solution:
We have,

It can be written as

![[\because (a^m)^n=a^{mn}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%5Em%29%5En%3Da%5E%7Bmn%7D%5D)
Taking log on both sides.
![\log [3((2^{2x})]=\log 5^(x+1)](https://tex.z-dn.net/?f=%5Clog%20%5B3%28%282%5E%7B2x%7D%29%5D%3D%5Clog%205%5E%28x%2B1%29)
![[\because \log (ab)=\log a+\log b]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog%20%28ab%29%3D%5Clog%20a%2B%5Clog%20b%5D)
![[\because \log x^n=n\log x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog%20x%5En%3Dn%5Clog%20x%5D)
Putting values of logarithms, we get
![[\because \log 2 =0.301, \log 3=0.477, \log 5=0.699]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog%202%20%3D0.301%2C%20%5Clog%203%3D0.477%2C%20%5Clog%205%3D0.699%5D)



Divide both sides by -0.097.



Therefore, the value of x is -2.289.
Answer:
7m+14 is the correct answer
