Answer:

a) 5/9

b) 7

c) 5

Step-by-step explanation:

For a)

One of the rules for logs is that if there is a logarithm subtracted by a logarithm and they have the same base, it is the same as the log with the same base and the arguments are divided:

$log_{x}z -log_{x} y$ = $log_{x} \frac{z}{y}$

so for this problem, they have the same base, so you can use this rule:

$log_{4} 5-log_{4}9 = log_{4}\frac{5}{9}$

For b)

This is very similar, except instead of dividing the arguments, you want to multiply them.

So this is kind of saying "8 multiplied by x equals 56"

which is 7

For c)

If the argument has its own exponent, it can be brought to the front of the log like so:

$log_{10}x^{y} = ylog_{10}x$

This one is a bit tricky because you have to actually set 32 into an exponent form first.

$32 = 2^{5}$

Then we can bring that 5 in front of the logarithm

$log_{6}2^{5} = 5log_{6}2$

So the answer is 5

The correct answer is: 
green and blue.

Explanation: 
We want to see which fractions $\frac{3}{4}$ is a multiple of. We know that $\frac{3}{4}$ is a multiple of $\frac{1}{4}$ , because $\frac{1}{4}$ *3= $\frac{3}{4}$ .

We can divide fractions to determine if $\frac{3}{4}$ is a multiple of $\frac{1}{2}$ :
$\frac{ \frac{3}{4}}{ \frac{1}{2}}$ ;

in order to divide fractions, flip the second one and multiply:
$\frac{3}{4}$ )* $\frac{2}{1}$ = $\frac{6}{4}$ =1 $\frac{1}{2}$ .
This did not divide evenly, so $\frac{3}{4}$ is not a multiple of 1/2.

Checking to see if $\frac{3}{4}$ is a multiple of $\frac{1}{8}$ , $\frac{ \frac{3}{4}}{ \frac{1}{8}}$ ;

flip the second one and multiply:
$\frac{3}{4}$ * $\frac{8}{1}$ = $\frac{24}{4}$ =6.
This divided evenly, so $\frac{3}{4}$ is a multiple of $\frac{1}{8}$ .
