(i) 2 x^{4}-16 x y^{3}\\ ன் காரணி

2 x\left(x^{3}-8 y^{3}\right)

\left(a^{3}-b^{3}\right)=(a-b)\left(a^{2}+a b+b^{2}\right)              

              =2 x\left(x^{3}-(2 y)^{3}\right)              

              =2 x\left((x-2 y)\left(x^{2}+(x)(2 y)+(2 y)^{2}\right)\right)

              =2 x(x-2 y)\left(x^{2}+2 x y+4 y^{2}\right)  

\text { (ii) } 8 x^{3}+27 y^{3}+64 z^{3}-72 x y z ன் காரணி

=(2 x)^{3}+(3 y)^{3}+(4 z)^{3}-3(2 x)(3 y)(4 z)

\begin{aligned}&=(2 x+3 y+4 z)\left(4 x^{2}+9 y^{2}+16 z^{2} - 6 x y-12 y z-8 x z)\end{aligned}.
