Answer 2

First of all thanks for asking this question..this kind of question sometimes asked in product based companies interview.

Interviewer know that no one can answer correctly without any instrument…he just wanna look your approach of solving this problem..and for your optimal answer…you can answer in this way..

2^100 = 2^10 * 2^ 10* 2^ 10* 2^ 10* 2^ 10* 2^ 10* 2^ 10* 2^ 10* 2^ 10* 2^ 10

because, 2^10 = 1024 ~ 1000

2^10 equals to 1024 but round figure value is 1000.

thats why,

2^100 =~ 1000 * 1000 * 1000 * 1000 * 1000 * 1000 * 1000 * 1000 * 1000 * 1000

=~ 1000000000000000000000000000000 approx

interviewer will say, congrats! you got a job…hahaha
