Comparing this to the general standard quadratic equation.
We have my
Is the goal to simplify? You just need to multiply the exponents for each factor:
(2z^2)^(-3)
= 2^(-3) x z^(2 x -3)
= (1/2)^3 x z^(-6)
= (1/8) x (1/z)^6
= 1/(8z^6)
Example: For every 3 boys, there are 4 girls.
Ratio: 3:4 also 3/4
How to use it?
Example question: If there are 3 boys for every 4 girls and there are 27 boys in the class, how many girls are there?

[Cross Multiply]
3x= 108
[Divide]
X= 36
How to check it?
Reduce 27/36 and see if it equals 3/4
OR
Plug both into the calculator and both should come out with the same decimal. In this case it is 0.75
