Y = x/5+1/5x i.e;y=x/6*1/5x y=x/30x.Now y=x/30x,Then y' is known as y dash, which is used for differentiation which is equiilavent to dy/dx.


we have equation-y=x/30x now take the variable y into the place of the denominator now it becomes x/30xy,which is equal to the differential fraction dx/dy where d is x .
The value of y is x/30x and the value of y' is x/30xy.

Hope you understood my answer please message me if I have comitted any mistake.

too good
Y = x/5+1/5x i.e; y=x/6*1/5x how did u get this?
