What is the derivative of LN ^ 2x?

What is the derivative of LN ^ 2x?

(ln²x)'=(2lnx)/x

Finding the tangent equation of function y = x + 2x at point (1,3) is a mathematical problem of derivative. I hope there is a process and explanation,

The process of solving the problem is as follows: the first step, derivation: y '= 2x + 2, the second step, tangent slope k = y' (1) = 2x1 + 2 = 4, the third step, tangent equation, know the slope, know a known point, using the point oblique formula: Y -- 3 = 4 (X -- 1), finishing: y = 4x -- 1, that is, you can continue to ask if you don't understand,
