Choose the correct simplification of the expression (2b/c)^3

A. 2b^3/c^3

C. 2b^3/c
D. 2b/c^3

I believe the correct answer is A. Is that right??

Answer 1

b

Answer 2

you have to cube the 2 as well, so a is not right

Answer 3

You can think about this as (2b/c)^3 * (2b/c)^3 * (2b/c)^3 = 8b^3/c^3.
So B.
