If you multiply together the number of fingers on every person's left-hands? (For the purposes of this exercise, thumbs count as fingers, for five fingers per hand) how long the number would be assuming 5 billion people on earth.

0. It would only take one person to have no fingers on their left hand to make it zero as anything multiplied by 0 is 0.

If all 5 billion people have 5 fingers on their left hand then the answer is 5^5 billion else answer will be 0 if any of this 5 billion people have no fingers on his/her left hand.

Point 1 : In the above post, user has posted two answers in one post, using an If Else statement. So either the last answer in the post should be counted. Or it should be considered invalid, as this is not there in the rule - "only one answer per post." Point 2 : Question is not clear, 5 fingers per person for only who have thumb or otherwise?

The only assumption here is we have 5 billion ppl on earth. We don't know if we have exceptions like someone without fingers on left hand etc .. There can be a lot of cases like some 1 has 1 finger, 2 fingers, 3 fingers .. no fingers etc.. And, I don't think it's possible to consider all of them. So.. i think the answer will be : The length of the number is = 5 billion * log(base 10) 5 = 5 * 10^9 * 0.69897000433601880478626110527551 = 3494850022 digits

5 fingers are considered and not 4 fingers and 1 thumb. Many are close or I must say quite close but still no perfect answers.

So the answer is 1. because the length of the number zero is 1. Or if you just want the length of 5^5000000000, that's easy enough too, with a little help from logs and a calculator: 5^5000000000=10^(log(5^5000000000)) =10^(5000000000*log(5)) 5000000000*log(5)=3494850021.6800940239313055263775 so the length of 5^5e9 is 3494850022

I thought we will end up with no current answer. 'coz every1 answered 0, but shabbir needed the length. Congratz xpi0t0s. :happy:

Kis type ka question tha yeh yaar?? :crazy: ... Kuch samaj main nahi aaya LOL...Question to door ki baat hai..answer bhi bouncer gaya...LOL

LOL, what is the length of this string ? "HELLO" 5 right? So what is the length of string 0? 1 Hence the answer is 1! why number of fingers = 0? Cause one of them will have no fingers in left hand, hence anything multiplied by 0 is = 0. Length of 0 = 1 Hence Ans = 1

Allright Shabir...My aplogies. mayjune..thanks for explaining..I think if i read it more than times..I would surely get it...
