Can someone help me with A

2^52

Step-by-step explanation:

Assuming that we have to just figure out another way of writing it, we can use one of the laws of exponents which is powers of powers so we multiply 13 and 4 and we get 2^52.  

2^52 is such a big number I'm not even going to solve it because I doubt that's what they want from you.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
