comment Differential equation $(x^2y^2-1)dy+2xy^3dx=0$
Problem didnt define what is t. However looking at it again it seems that this is a way to solve the resulting Linear ODE ?(after using $ X=x^2$ ) Setting $t=y^3$ ?

comment Differential equation $(x^2y^2-1)dy+2xy^3dx=0$
Seems a nice solution. But I have two questions. Why it requires $y=t^n$ ? Also why in mathematica I got that result ?

comment How to solve the differential equation $(x^{2}t(x)^{2n} - 1)nt(x)^{n-1}dt + 2xt(x)^{3n}dx = 0$
Original problem had y and required to use $t=y^n$

comment $y=e^{-x}$ and $y=x$ point of intersection
Amzoti no. I am studying definite integrals and need to find the intersection point in order to find the area starting from x=0

comment Evaluate $\int\sqrt[5]{\frac{x+5}{x-5}}\,\mathrm dx$
Could you explain how the last one could be solved ?
