We'll re-write the given expression, isolating dy:

dy = (3x^5 + 6e^2x)dx

We'll integrate both sides:

Int dy = Int  (3x^5 + 6e^2x)dx

We'll use the property of integral to be additive:

Int dy = Int 3x^5dx  + Int 6e^2xdx

Int dy =3x^6/6 + 6e^2x/2+ C

Int dy =x^6/2 + 3e^2x+ C

But Int dy = y, therefore y = x^6/2 + 3e^2x+ C, where C represents a constant.
