You just need to equate the expressions to find the values for a,b and c. First, let's settle that 2^5/4=8, and 8 is 2^3. Also, an important tool here is the indicie rule:
1st expression: 2^5/4=8
2nd expression: It tells us that 2^5/2^a=2^3 (I know that this equals to 8 as all the expressions are equal therefore is the same as our first expression). Using the indicie law, this means that a=2
3rd expression: 2^b must equal to 8 as well, so b=3
4th expression: c=8 as all of the other expressions we have figured out equal to 8
So a=2, b=3 and c=8

Answer:
x = 5
Step-by-step explanation:
Given
=
( cross- multiply )
16x = 80 ( divide both sides by 16 )
x = 5
Use these equations when converting polar equations to parametric equations:
We know that , so substitute that into both equations for x and y.
Now, replace with any variable that you want to represent the parametric equations in. I'll use the standard variable,
Thus, represented in parametric form is:
