ok so the final answer would b a) y' = -(y + 5x^4y^2 + 9x^2)/(x+2x^5y) and b) y' = -y sin x thank you SO much once again steve, my exam is in a couple of hours and this solution really helped me, im very thankful. thanks so much!!

thank for you so much steve!!! i just wanted to double check.. for (a) it is y' = - (y+5x^4y^2+9x^2)/(x+2x^5y) i was wondering if the last part of it (x+2x^5y) is it 2x^(5y) or 2x^5(y). im not sure if the "y" is in the exponent or not.
