Am i supposed to find a calculator that will show all of the numbers? Does anyone on here know of one?

If I calculate (17**39)**11 I'm getting a number with 528 digits, which (conveniently) is 16*33. Now if I split that number into blocks of 33 digits, and write down the last digit of each block, I get a certain 16 digit number starting with 26 and ending with 07. But I'm told that this is not the correct answer.
Now, if I take the first digit, and every 33rd from there (1st, 34th, 67th, ...) I get a number starting with 76 and ending with 77, which apparently is wrong too.

Do I need to apply any conversion? Or did my calculator (bc) do something wrong here? Or did I misinterpret the description (non-native english speaker)?

You should submit the 1st, 34th, etc digits. One of the digits you quoted (76......77) was wrong. Maybe you miscounted the digits, if you did it by hand.

No miscount, looked at the wrong column after I broke it into groups. Shouldn't do these at 1 in the morning. Thanks

right. but i wouldnt have solved this one without your hint.. the question is easily misunderstood as:

33rd = the "first, most significant"

66th
99th
...

Karen's power tools calculator has come in handy for this and other challenges; it allows for long values.

I've made my own multiply function
if u know the math trick
(17**39)**11 = 17**(39*11)

that trick is pretty useless here. either way you have a hard time without the right tools..

How do i enter this sum into Karen's power tools? Also so far my computer has been unable to come with anything up to 17^16, so i don't see how I'm supposed to complete this task.

(Ive times 17 by 17 and then I've been pressing = to times it by 17 over and over again, I've only been ably to get to 17^16, after that it takes around half an hour per sum.

maybe u will need a program to solve this

... I use Java->BigInteger to did it.

Powerful hand calculators are useful here too...

python can do it, it might take a while though

Really? In python, it was a one-liner for me that took no noticeable time to run.

oops, i was thinking of a different challenge

Any powerful web calculator that anyone would recommend?
MS Calculator is totally useless, and I don't know how the script goes in PHP, nor do I know any other coding language to solve the problem with.

Thanks in advance.
