Find the coefficient of `1/y^2 ` in `(y+ c^3/y^2)^10`

Find the co-efficient of y^4 in (y+c^3/y^2)^10 .

The coefficient of y in the expansion of (y^(2) + c//y)^(5) is

If fly)=1-(y-1)+(y-1)^(2)-(y-1)^(3)+...-(y-1) then the coefficient of y^(2) in it is

If (x^2y + y^2 + 3) is subtracted from (3x^2+y + 2y^2 + 5) , then coefficient of y in the result is _______ .

Find the value of y: y/4 - 1/2 = y/3

Find the product :- (y + 1/y)(y - 1/y)(y^2 + 1/(y^2))

"Find the value of "(x+y)," if "(x+(y^(3))/(x^(2)))^(-1)-((x^(2))/(y)+(y^(2))/(x))^(-1)+((x^(3))/(y^(2))+y)^(-1)=(1)/(3)
