(1 point) a bernoulli differential equation is one of the form dydx+p(x)y=q(x)yn. observe that, if n=0 or 1, the bernoulli equation is linear. for other values of n, the substitution u=y1−n transforms the bernoulli equation into the linear equation dudx+(1−n)p(x)u=(1−n)q(x). use an appropriate substitution to solve the equation y′−3xy=y5x3, and find the solution that satisfies y(1)=1.
