Ok so I have a few problems here that I have to know how to do for a test I have. If you can do at least one of them that would be awesome, + rep. I'm pretty sure how to do some of them but I need to double check. Differentiate the following. 1. y=ln(x+4)/(x^3) 2. y=3^(4x^5) 3. y=log6(x^6) 4. y=x^2e + e^(-2x) 5. y=ln (x-8)/(x^8) 6. y=(x^2)e^x 7. y= (1/3)e^(6x^3) Word problems. 1. Find the equation of the tangent to y=x^(3x) @ x=1 2.Find the values of k in y=e^(kx) so that y is a solution of y''+3y'+ 2y=0 Any help is greatly appreciated. EDIT: NVM too late, I g2g. Someone lock this board plz.
