$$(x^3 - y^6)(x^3 + y^6)$$ is equal to
Given :Â $$(x^3 - y^6)(x^3 - y^6)$$
As we know,Â
$$a^x\times\ a^y=a^{\left(x+y\right)}$$
Lets solve it :Â
$$=\left(x^3\times\ x^3\right)+\left(x^3\times\ y^6\right)-\left(y^6\times\ x^3\right)-\left(y^6\times\ y^6\right)$$
$$=\left(x^6\right)+\left(x^3\times\ y^6\right)-\left(y^6\times\ x^3\right)-\left(y^{12}\right)$$
$$=\left(x^6\right)-\left(y^{12}\right)$$
Hence, Option D is correct.Â
