If f(z)=m^z - n^z <span>and f(1)=2, f(2)=8
then
m - n = 2 so m = n + 2
m^2 - n^2 = 8
substitute </span>m = n + 2 into m^2 - n^2 = 8
so
m^2 - n^2 = 8
(n + 2)^2 - n^2 = 8
n^2 + 4n + 4 - n^2 = 8
4n = 4
n = 1
m = n + 2 = 1 + 2 = 3
so f(z) = 3^z - 1^z
if z = 1 the f(1) = 3^1 - 1^1 = 2
if z = 2 the f(2) = 3^2 - 1^2 = 9 - 1 = 8
if z = 3 the f(3) = 3^3 - 1^2 = 27 - 1 = 26
answer
f(3) = 26
Let's see
Total votes be x
- 45% of x=3600
- 0.45x=3600
- x=3600/0.45
- x=8000
Now total percentage of vote
Not voted=4%
Find not voted

If you would like to solve the equation 3 3/4 * a + 3 + 6 = 87, you can do it using the following steps:
3 3/4 * a + 3 + 6 = 87
15/4 * a = 87 - 3 - 6
15/4 * a = 78 /*4/15
a = 78 * 4/15
a = 104/5
a = 20.8
The correct result is 20.8.
