## Homework Statement

if a value has a variables that cancel out can it be considered a constant?

looking to make an equation out of proportionality statements

## Homework Equations

this is the equation that we are supposed to get: f=√((F)/(4∏

^{2}mr))

the 3 proportionality where f

^{2}=kF , f= k(1/m) and f= k(1/r)

## The Attempt at a Solution

i have reached here : f

^{2}= k(F/m

^{2}r

^{2})

k being a constant, can its value be : k= (mr)/(4∏

^{2})

so that the values cancel out giving you the required equation?

and would it still be considered a constant?
