Use logb^2=.4307 and logb^3 - .6826 to evaluate logb18

Log b 18 = logb 2 * 3 * 3

When multiplying logs, they are added together so:

logb 2 * 3 * 3 = logb 2 + logb 3 + logb 3

Logb 2 is given as 0.4307 and logb 3 is 0.6826

Now we have 0.4307 + 0.6826 + 0.6826 = 1.7959

Logb 18 = 1.7959

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.

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
