The product of two powers with the same exponent
is a power where the product of the bases is raised to the same common exponent.
Similarly, the product of two roots with the same index
is the root with the same index of the product of the expressions inside each radical.
So, ==
When simplifying you have to figure out the smarter way of factoring, and in
I factored cubes out of each part/factor in
(The parts I am talking about are the coefficient (128), the power of , and the power of ).
is a cube.
From the other parts I factored out the greatest cube I could factor out:
.
