it with the amount of hair your sister has and you kept multiplying this with the people (let's say in your church or an organization), approximately what would be your answer?

for example you have 1000 strands of hair on your head x 1000 hairs on your sister head, x 1000 hairs on your boy friends head, etc... and you did this multiplying with the people in your church or class.... what would your approximate number be?

you guys are ALL wrong! The answer would be ZERO! All it takes is one bald guy, because if you multiply any number by "0" your answer would be "ZERO"!!!!!!

The human head has approximately 100,000 hair follicles. That's 10^5.
If you multiply that times the number of hairs on your sister, that would be 100,000 x 100,000 = 10^5 x 10^5.
Remember to add exponents when multiplying powers of 10. So this is equivalent to 10^10
Now let's assume there are 20 people in your church. You would repeat the process a total of 20 times.
10^5 x 10^5 x 10^5 x ... x 10^5 {20 times}
That's the same as 10^100. We are up to a googol, just with 20 people.
*The number 100,000 (10^5) came from several sources, including Wikipedia.
In general, if you had N people, the product would be:
(10^5)^N
This is the same as:
10^(5N)
Edit: Drat! You got me with the bald headed person. I was just thinking of a classroom of young students where baldness is unlikely. And even in my church congregation there isn't anyone that is 100% bald... thinning, yes... complete baldness, no.
Anyway, good job tricking us with that!

are you talking about the number of hairs or the total mass of the hair?
In any event, your answer would be (approximately) the amount for the average person to the power of however many people you are talking about.
** I don't know anybody who is totally bald, as in not even 1 hair

There are approximately 100,000 hairs on a human head.
That is 10to the fifth power ie 10^5.
therefore the answer to your question is (10^5) ^ the number of people involved, for example 6 people. (10^5)^6 IE 10^30

Ultimately I shall get the product equal to ZERO due to one totally bald person.

Are we talking just head hair, or does body hair count too?

I'm not sure abou this one, but somewhere above 100, I would say.
