Given y=Ax^r where A and r are constants, how can you show that it will give a straight line on a log-log graph. Obviously selecting various values for A and r gives you a straight line on a log-log graph but how can you show that in generality?

Can somene please show me the algebraic steps of how I get from z= 1/ ( √1-rs/r) -1z= gravitaional redshiftto make it look like r/rs= 1/ [1-(1/z+1)^2 ]I have no clue how to flip the rs/r into r/rsthanks so much

Hey, I'm unsure of how to propagate the equation, u{C}=C xv((u{RC}/RC)^2+(u{R}/R)^2 ). Can someone please help me?
