Hey guys, I got two problems here, that are probably extremely basic; but i'm having a hard time with these. When I finally find a -substitution path I can generally work my way through, but I'm hitting a block on these, even just a pointer or what should be would be great!
For this one, I'm trying to find a sub but I can't seem to make it work, I keep wishing real hard that the was under the radical and the was outside.
Again, no idea what to set equal to because there is no with the
Any toss as to where to go next would be great, thanks for taking a look!
