Differential equation:
Equation y'=(2y^4+x^4)/(xy^3)
Equation y"+4y=cos2x
Equation y"-7y=0
Equation d^2y/dx^2-2*dy/dx-3y=0
Identical expressions
y'=(2y^ four +x^ four)/(xy^ three)
y stroke first (1st) order equally (2y to the power of 4 plus x to the power of 4) divide by (xy cubed )
y stroke first (1st) order equally (2y to the power of four plus x to the power of four) divide by (xy to the power of three)
y'=(2y4+x4)/(xy3)
y'=2y4+x4/xy3
y'=(2y⁴+x⁴)/(xy³)
y'=(2y to the power of 4+x to the power of 4)/(xy to the power of 3)
y'=2y^4+x^4/xy^3
y'=(2y^4+x^4) divide by (xy^3)
Similar expressions
y'=(2y^4-x^4)/(xy^3)

Differential equation y'=(2y^4+x^4)/(xy^3)

The teacher will be very surprised to see your correct solution 😉
