Formula use: \left(a+b\right)^3=a^3+3.a^2.b+3.a.b^2+b^3
Here, given expression is v
Find the cubes with the help of formula :
\left(a^2+bc\right)^3
\rightarrow\left(a^2\right)^3+3.\left(a^2\right)^2.bc+3.a^2.\left(bc\right)^2+\left(b\right)^3 [use formula]
\rightarrow a^6+3a^4bc+3a^2b^2c^2+b^3
Ans: a^6+3a^4bc+3a^2b^2c^2+b^3\ .
