Find the value of n so that the subnormal at any point on the curve `xy^n = a^(n+1)` may be constant.

If the subnormal at any point on the curve y^(n) = ax is a constant, then n=

The sub normals at any point of the curve y = x^(n) is constant. Then n=

Find the value of k, so that the length of the subnormal at any point on the curve xy^(k)=a^(k+1) is a constant.

Find the value of k, so that the length of the subnormal at any point on the curve y=a^(1-k)x^(k) is a constant

The value of n for which the length of the sub- normal at any point of the curve y^(3)=a^(1-n)x^(2n) must be constant is
