Answer:

Step-by-step explanation:

$\frac{3}{4} -4x+\frac{1}{2} x-\frac{1}{2} +\frac{1}{2} x\\=\frac{3}{4} -\frac{1}{2}-4 x+\frac{1}{2}x+\frac{1}{2} x\\=\frac{3-2}{4} -4x+\frac{1+1}{2} x\\=\frac{1}{4} -4x+\frac{2}{2} x\\=\frac{1}{4} -3x$

First lets start with number six. The only way to solve this is if you determine what "a" and "b" are using the first log they have given to you. $log_a_ba=\frac{1}{3}$

The first variable that I solved for was "a" and $a=e^\frac{in(b)}{2}[tex]{[tex] 0$ }

The same is also true for "b", but when you put both "a" and "b" together the only combination that I have found to work is $a=\frac{1}{2} , b=\frac{1}{4}$

Next you plug these numbers in for "a" and "b" on the second equation to get something that looks like this: $log_\frac{1}{2}_*_\frac{1}{4} (\frac{\sqrt{\frac{1}{2}}}{\sqrt[3]{\frac{1}{4}}} )= -\frac{1}{18}$ and the picture below shows where the answer becomes a negative fraction.

Next is #7, the easier of the two.There are two ways to solve for your answers. According to the graph of this equation there are four possible real solutions. $x=2,-2,\sqrt{2}, and -\sqrt{2}$ . (This does not account for any complex solutions)
