Question 84532: ((2x)^2)((4x)^4)((8x)^6)=
a.) (2^22)(x^12)
b.) (2^24)(x^12)
c.) (2^26)(x^12)
d.) (2^28)(x^12)
I know the answer is d. but how would you arrive at that answer without multiple choice answer. Say this was on a test and it wasn't multiple choice, how would you arrive at the correct answer in that format. I understand how to get the x^12 but I do not know how to arrive at 2^28. How do get from 268435456 to 2^28?

Question 85835: I know this is a very basic question, but I cannot remember if there is any way of figuring 1.02^20 other than the traditional long way of doing 1.02x1.02x1.02 etc etc. Is there an easier formula or way to do this?
I also need to know if 10% changed to a decimal is .010 or .10
Thank you.
