Answer:
C -- [tex]192y^8[/tex]
Step-by-step explanation:
First, simplify [tex](4y^2)^3[/tex]. Use exponential rules (power to a power = multiply powers, number to a power times number to a power = add powers)
[tex](4y^2)^3\\=4^3*(y^2)^3\\=64*y^6[/tex]
Therefore,
[tex](4y^2)^3(3y^2)=(64y^6)(3y^2)\\=192y^8[/tex]
