Answer 1

Answer:28

Step-by-step explanation:

-Write down the factors of  

784  and and see if they share the same with the choices.

- For example, if you see  

27 and  29 , you can tell that there is no factor of  27  or  29  in 576 since they are prime number and eliminate them.

- At this time you verify one by multiplying  28 × 28  to verify.

Recheck:

28 × 28 = 784
