Answer:

A is least

Step-by-step explanation:

A= 560

B= 630

C= 568

D= 639

If you do 7 x 10 which equals 70 then do 70 by the power of 8 which is multiplying 70 8 times, you get 560 which is the least equation/answer out of all of them.

A.10*8=100000000×7= 700000000

C.10*8=100000000×7.1=710000000
