implicit diff yes?

Answer 2

@satellite73 Do You Think You Can Help With A Problem?

Answer 3

\[ x\ln(y)+y^5=7\ln(x)\]
the right side is easy, it is \[\frac{7}{x}\] the left side requires the product and chain rule

Answer 4

yep yep

Answer 5

\[\ln(y)+x\frac{1}{y}y'+5y^4y'=\frac{7}{x}\] is a start

Answer 6

Thanks! I just need a start and can go from there. The online website we have to enter isn't made very well so it's always a struggle entering the answers.

Answer 7

is it clear how i got that? that is really the only concept part, the rest is algebra

Answer 8

Yeah it makes sense now. The algebra of it is pretty easy, to start it off is what's confusing

Answer 9

ok good
