Hey Gary :) Nice to see you around

For this question, we want to use logarithmic rules to write the expression as a single logarithm.
Using the rule $log_{b} ( M^{k} ) = k * log_{b} M$ , we can simplify
$3log_{b} q$ to $log_{b} ( q^{3} )$ . We can also simplify $6log_{b}(v)$ to $log_{b}( v^{6})$ .

So, we have $log_{b} ( q^{3} )$ + $log_{b}( v^{6})$ .

Another logarithmic rule is:
$log_{b}(M*N) = log_{b} M + log_{b} N
$

Using this rule, we can use the logs we have calculated and change them to:
$log_{b}( q^{3} v^{6})$

This matches answer choice A.

Hope this helps! Feel free to contact me with any questions.

In brighton, 90 homes receive papers each day. When would Brendan and Denny need to wake up to deliver all their papers by 8am?

maksim [4K]

If they deliver 44 per hour together, and brighton gets 90 papers, 2 hours would be waking up at 6 am

In a psychology class, 44 students have a mean score of 96.6 on a test. Then 13 more students take the test and their mean score

NikAS [45]

Answer: 89.7

Step-by-step explanation:

The mean of a data set is the average of all the information given. Therefore, the total combined score is the number of students multiplied by the mean

The total score of the first 44 students: 96.6*44 = 4250.4

The total score of the later 13 students: 66.3*13 = 861.9

(4250.4 + 861.9)/(44 + 13) = 89.7

Hope this helped

Please guys help me out with this

When you have a negative exponent, you move the variable with the negative exponent to the other side of the fraction to make the exponent positive.

For example:

$x^{-2}$ or $\frac{x^{-2}}{1} =\frac{1}{x^2}$

$\frac{1}{2y^{-3}} =\frac{y^3}{2}$ (you don't move the "2" because "2" has an exponent of 1, only "y" has the negative exponent)

$\frac{5^{-2}}{y}=\frac{1}{(5^2)y} =\frac{1}{25y}$

When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together. (But you can only combine the exponents when the variables are the same)

$x^2(y^3)=x^2y^3$ (You can't combine them because they have different variables of x and y)

$x^3(x^5)=x^{(3+5)}=x^8$

$y^3(y^2)=y^{(3+2)}=y^5$

There's two ways you can do this. Either by first making all the exponents positive then do subtraction, or multiply them then make all the exponents positive. I'm doing the 2nd way.

$2w^7u^{-2}w^{-6}*9y^{-6}*2y^9u$ You can combine the numbers 2 x 9 x 2 = 36

$36w^7u^{-2}w^{-6}y^{-6}y^9u$ Now multiply the terms with the same variables

$36(w^{7+(-6)})(u^{(-2+1)})(y^{(-6+9)})$

$36(w^1)(u^{-1})(y^3)$ Now make all the exponents positive

$\frac{36wy^3}{u}$

If you were to do subtraction, here is what you need to know:

When you divide a variable with an exponent by a variable with an exponent, you subtract the exponents together. (Reminder: they have to be the same variable in order to combine the exponents)

For example:

$\frac{x^3}{x^2} =x^{(3-2)}=x^1$ or x

$\frac{y^2}{y^4} =y^{(2-4)}=y^{-2}=\frac{1}{y^2}$

The answer to this is Thursday. All you do is look on a Calendar on a Monday. Then count 39 days later. And it will be a Thursday.
