Simplify
ivolga24 [154]
The correct answer is:  [A]:  " \frac{8}{729} " .
_________________________________________________________
Explanation:
_________________________________________________________
We are asked to simplify:

                  →    (\frac{2}{9})^3   

_________________________________________________________
Note the following property of exponents:
_________________________________________________________

( \frac{a}{b})^n  =  \frac{(a^n)}{(b^n)} ;  { b \neq0 } . 

_________________________________________________________
As such:

→  ( \frac{2}{9})^3  ;

                 
 =
\frac{2^3}{9^3} = \frac{(2*2*2)}{(9*9*9)} =  \frac{8}{729} .

_____________________________________________________________


The answer is:  
" \frac{8}{729} "  ; 

→  which is:  "Answer choice:  [A]:  " \frac{8}{729} " . 
_____________________________________________________________
Hope this answer—and explanation—is of some help to you.
