License plates in China begin with a Chinese character designating the province, followed by a letter from the set {A,....,Z}, followed by a five character alphanumeric string (using symbols from the set {A,...,Z,0,1,....9}). What is the maximum number of plates of this type for a given Chinese province. ?
I guess
26*
I guess
26*
that is, multiply the number of possible characters in each postion

26*3*3

where is 3 coming from? And why only 2 of them? There are 5 positions.
26 is the correct for the first character.
how many characters for the second? multiply that, then how many for the third, multiply that, and so on.
Look at the previous question. See the pattern?

Techn9cian - no that's not correct (your math is right, but the answer to this question is wrong)
also, it's clear I was trying to help him understand "how" to do it.
I gave the answer directly last time because he appeared to be on the right track. In this case the attemp 26* appears to be just a random guess. So I'm walking through the logic

I didn't see the 0, sorry.

http:#37008033 and http:#37008079 and http:#37008085 are saying the same thing.
Does it make sense?

set {A,...,Z,0,1,....9})
A....Z=26+0+9
it should be 36 because of zero. I may be wrong:
26*36*36*36*36*36
A....Z=26+0+9
it should be 36 because of zero. I may be wrong:
26*36*36*36*36*36
yes exactly!
26 for the first
36 for each of the following 5
you simply multiply the number available for each position
or in power notation 26*36^5 same thing, just different way of writing it

How to convert this number into 2 raise to power ?

or you can calculate it directly with any language or calculator that has a LOG or LN function
log(1572120576) / log(2)
ln(1572120576) / ln(2)
some languages may let you specify the base of your log though
if you have one of those, try log(2,1572120576)
log(1572120576) / log(2)
ln(1572120576) / ln(2)
some languages may let you specify the base of your log though
if you have one of those, try log(2,1572120576)
what is that supposed to be? I don't understand your guess.
In any case, this is essentially the same as your previous question.
