if `y=x^n` then `y_2 =`

If y=x^(n-1)ln x then x^(2)y_(2)+(3-2n)xy_(1) is equal to -(n-1)^(2)y(b)(n-1)^(2)y-n^(2)y(d)n^(2)y

If (x+y)^(m+n)=x^my^n then dy/dx= (A) x/y (B) -y/x (C) -x/y (D) y/x

If y=x^(2)log x, then value of y_(n) is

If "(dy)/(dx)+(2y)/(x)=0 ,y(1)=1" then y(2)=(1)/(n') "(n in N)" .value of "n" is

If 2x=y^(1//n)," then: "x^(2)(y_(1))^(2)=

If x^(2)y^(3)=(x+y)^(n+2) and (dy)/(dx)=y/x then n=
