...I have no idea how to answer these problems

Solve for x

ln((x-4)^2)=14

solve for x

Find an equation of the tangent line to the graph of the function at the point (1, 1).

1+ln(xy)=e^x

implicit derivative ...

determine the slope at the indicated coordinates, then write the tangent line equation.

Solve the differential equation

dy/dx=(9e^x-2e^-x)^2
