Question

I need help with a implicit diff. problem...
Ln(15x^7)-3y^3=x^3e^y... i need to find y prime,.. got stuck.. any help???

Answer 1

is it\[x^{3e^{y}}\]or\[x^3e^y\]

Answer 2

the second one

Answer 3

\[7/x-9y^2(dy/dx)=3x^2e^y+x^3e^y(dy/dx)\]
combine the dy/dx
\[(7-3x^2e^y)/x(9y^2+x^2e^y)=dy/dx\]
