i think finding r exactly is pretty much impossible here, there are too many unknowns. as earboth suggested, they probably want us to prove that the left hand side is the same as the right hand side...or wait! maybe not! maybe we could find r....

pick up where earboth left off.

Now we are told that

.......since, if

and you can plug that into your calculator to see what it is
