What are the four laws of radicals?
Remove radical signs if possible.
Make the radicand as small as possible.
m/n must be in simplest form.
Rationalize the denominator if applicable.
What is a direct variation?
Direct dependency
If x increases, y increases.
What is an inverse variation?
Quantity changes go opposing ways.
If x increases, y decreases
What is a joint variation?
Direct dependency between more than two variables.
If x and y increase, z increases.
What is a combined variation?
In which a variable is directly dependent on one and inversely on another.
If x increases, y increases. if z increases, y decreases.
