Flura [38]

Answer:

The x's cancel  so definitely is choice C:  1/9

Step-by-step explanation:

We have   root( 1/(x^2) )  *  root ((x^2) / 81)

simplifying this we get as follows:

root( 1/(x^2) )  *  root ((x^2) / 81)

= \sqrt{(1/x^2 )}  * \sqrt{(x^2)/81}

=  ( 1/x )   *  (x/9)

the x's cancel

= 1/9

choice C   1/9
