MCQ

Baylee tried to solve the differential equation dydx=exy2\frac{d y}{d x}=\frac{e^{x}}{y^{2}}.
This is her work:
dydx=exy2.\quad \quad\frac{d y}{d x}=\frac{e^{x}}{y^{2}} .

Step 1:- y2dy=exdx\int y^2 d y=\int e^x d x

Step 2:-y33=ex\frac{y^3}{3}=e^x

Step 3:-y3=3exy^3=3 e^x

Step 4:
Is Baylee’s work correct? If not, what is her mistake?

Select all that apply :

Step 2 is incorrect. The right hand side of the equation should be ex+ce^{x}+c.

Baylee’s work is correct.

Step 1 is incorrect. The separation of variables was not done properly.

Step 4 is incorrect. The right hand side of the equation should be
