Expression given:


64t^3+125v^6

Factoring:

0. Applying the Law of exponents


64t^3+125v^6=\mleft(4t\mright)^3+\mleft(5v^2\mright)^3

2. D = Sum of Cubes:


=(4t)^3+(5v^2)^3=(4t+5v^2)((4t)^2-4t\cdot\: 5v^2+(5v^2)^2)

Simplifying:


=\mleft(4t+5v^2\mright)\mleft(16t^2-20tv^2+25v^4\mright)

Then, the only Factoring Pattern we need is D.

Answer: D.
