SOLUTION: I just recently started this unit and I am so confused. They said to evaluate the following and this is their answer: 8^5 x 4^2 / 2^16 = 2^15 x 2^4 / 2^16 = 2^3 = 8

Question 892993: I just recently started this unit and I am so confused. They said to evaluate the following and this is their answer:
8^5 x 4^2 / 2^16
= 2^15 x 2^4 / 2^16
= 2^3
= 8
My question is how did they derive at ^15 and ^4 and ^16. ? Your help is much appreciated. Thank you.
