To simplify the expression (4^3)^2/4^2, we can follow the order of operations (PEMDAS/BODMAS) which states that exponents should be simplified before division.
(4^3)^2 means we raise 4 to the power of 3 first, so (4^3)^2 = 64^2 = 4096.
Then we have 4096/4^2. Since 4^2 is 16, we can substitute it into the expression:
4096/16 = 256.
Therefore, the equivalent single power to the expression (4^3)^2/4^2 is 256.
