Since it involves cube root, we are going to find prime factors of 8 and a^12
8 = 2*2*2
= 2^3
a^12 = a*a*a*a*a*a*a*a*a*a*a*a
= a^3*a^3*a^3*a^3
= (a^3)^4
Therefore the cube root of 8a^12 is 2a^4

I think you mean:
:
CubeRt(8*a^12)
:
Think of this as factored to
:
CubeRt[2*2*2*a^4*a^4*a^4]
:
Extracting the cube root gives you:
:
2*a^4
:
