log(y2)\log{\left(y^{2} \right)}
log(y^2)
Detail solution
  1. Let u=y2u = y^{2}.

  2. The derivative of log(u)\log{\left(u \right)} is 1u\frac{1}{u}.

  3. Then, apply the chain rule. Multiply by ddyy2\frac{d}{d y} y^{2}:

    1. Apply the power rule: y2y^{2} goes to 2y2 y

    The result of the chain rule is:

    2y\frac{2}{y}


The answer is:

2y\frac{2}{y}
