Let α,β be the roots of the equation, ax2+bx+c=0.a,b,c are real and sn=αn+βn and \(\begin{vmatrix}3 &1+s_1 &1+s_2\\1+s_1&1+s_2 &1+s_3\\1+s_2&1+s_3 &1+s_4\end{vmatrix}=\frac{k(a+b+c)^2}{a^4}\) then k=
The mode of reproduction in which a new offspring is produced by a single parent is known as asexual reproduction. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.
