Condense the following logarithm: 5log_4(a) - 6log_4(b)

grin007 [14]

Hi there! We are given the expression:

$\large \boxed{5 log_{4}(a) - 6 log_{4}(b) }$

To condense or simplify the following logarithm. You have to remember these properties:

Properties - Logarithm

$\large{ log_{b}(a)^{n} = n log_{b}(a) } \\ \large{ log_{b}(a) - log_{b}(c) = log_{b}( \frac{a}{c} ) }$

These two properties are what we need for our problem. Therefore,

$\large{ log_{4}(a)^{5} - log_{4}(b)^{6} }$

We use the log_b(a)^n = nlog_b(a) property to convert in the form above. Next, we use the second property.

$\large{ log_{4}( \frac{ {a}^{5} }{ {b}^{6} } ) }$

Answer

log base 4 of (a^5/b^6) is our simplifed form.

Any questions can be asked through comment as I may reply soon. Thanks for using Brainly! Have a good day and happy learning! :)

When a class took a math test, 15% of the class failed, 25% made some mistakes (but didn’t fail), and 24 students got perfect sc

mart [117]

Answer:

There are 40 students in the class.

Step-by-step explanation:

We are given the following in the question:

Percentage of class that failed = 15%

Percentage of class that made mistakes but did not fail = 25%

Number of students that got perfect score = 24

Percentage of students that got perfect score =

$100\%-\text{Percentage of class that failed}-\text{Percentage of class that made mistakes but did not fail}\\= 100\%-15\%-25\%\\= 60\%$

Let x be the total number of students in the class.

Then, we can write:

$60\% \text{ of } x = 24\\60\% \times x = 24\\\\\displaystyle\frac{60}{100}\times x = 24\\\\x = 24\times \frac{100}{60}\\\\x = 40$

Thus, there are 40 students in the class.

Yesterday it took 5 cleaners 4 and 1/2 hours to clean all the rooms in a hotel. There are only 3 cleaners to clean all the rooms

beks73 [17]

If 5 cleaners took 4 hours and 30 min. to clean the whole rooms in a hotel and there's only 3 cleaners, it would take them 6 hours and 30 min. why? because 5 cleaners = 4 hours and 30 min. 4 cleaners = 5 hours ad 30 min. 3 cleaners = 6 hours and 30 min. Anyway so, if they were paid 8.20 for each hour you would multuply that so 8.20x6.5 = ?? and then you divide the answer to 3 and thats your answer
