Could someone please show me the intermediate steps of rewriting this
$$\pi(p,w) = p(\frac{w}{pa})^{\frac{a}{a-1}}-w(\frac{w}{pa})^{\frac{1}{a-1}}$$
to this
$$\pi(p,w) = w(\frac{1-a}{a})(\frac{w}{ap})^{\frac{1}{a-1}}$$
reinout
Thank you Alan,
I made some foolish mistake at
$$p*(\frac{w}{p*a})^{\frac{a}{a-1}} = p*(\frac{w}{p*a})^{\frac{a-1}{a-1}+ \frac{1}{a-1}}$$
Thank you
