What is the true solution to the equation below 2 log3(6x)-log3(4x)=2 log 3(x+2)
a. x=-2 and x=1
b. x= -2 and x=2
c. x=1 and x=4
d. x=2 and x=4
it's c

The answer is (C) C. x=1 and x=4.

Step-by-step explanation: We are given to find the true solution of the following equation involving logarithms:

We will be using the following properties of logarithms in the solution.

The solution is as follows:

Since we can find the logarithm of a positive integer only, and both the solutions x = 1 and 4 satisfy this condition after substituting in the given equation, so both the solutions are TRUE.

Thus, the correct option is (C).

C: x=1 and x=4  

Step-by-step explanation:

On edg

answer: add the !

step-by-step explanation: then we will answer

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
