Answer: 2, 4, 5, 8, 10, 16, 20, 25 . . . . Right!
(B) Explore the prime factors of these denominators.
What do they all have in common?
Did you even look at the prime factors?
$\displaystyle \begin{array}{ccc}2 &=& 2 \\ 4 &=&2^2 \\ 5 & = & 5 \\ 8 &=&2^3 \\ 10 & =& 2\cdot5 \\ 16 &=&2^4 \\ 20 &=&2^2\cdot5 \\ 25 &=&5^2 \end{array}$
Notice anything?
