ehsan: 2*(1+2*y)^(2/3)=(1*y)^(5/3)*.02^(.5)
Are you sure that this question is written correctly.
This was too difficult to do by hand and I think that the answer given is an approximation because sqrt(0.02) is an irrational number and i have done enough of the algebra to think that the irrational bit doesn't just cancel out.
I tried to do this in the site calculator but it didn't give me a final answer.
