Hi. I am having trouble getting started with this equation. Could you please help me?
the equation is w=Cr^-2. I need to solve this, but have no clue how to even start. Thanks for your help.
 


Hello mkgriffith06:

First, a comment about notation. When typing exponents that contain something more than a whole number, they're easier to read when enclosed in parentheses.

w = C * r^(-2)

The instruction to 'solve this' is ambiguous. We cannot determine a value for any of the numbers w, C, or r without first knowing the values of the other two.

As it's written, the given equation is solved for w.

We could solve this equation for C (i.e., use rules of algebra to rewrite the equation so that variable C is all by itself on one side of the equal sign).

We could also solve this equation for r (i.e., rewrite the equation so that r is all by itself).

Can you provide ALL of the instructions that came with this exercise?

Cheers,

~ Mark
