If y ¤ x = y2x for all positive integers, then (3 ¤ 4) ¤ 2 =
A. 38
B. 312
C. 316
D. 324
E. 332
The ¤ symbol tells us what operation to carry out on x and y
Carry out the same procedure on 3 and 4 first. So 38 is the result.
Now carry out the procedure on 38 and 2. So (38)4 is the result, which is equivalent to 332
