ANSWERS: 5
  • What you have displayed is a simple sequence of numbers. Do you have a question in there?
  • 4 zeroes... if by ....... you mean count all the evens between 10 and 196 as factors then forget it... i have more questions to answer in that period of time *.* good question though
  • 42 zeroes multiplying by a multple of 10 adds a zero (20 times) multiplying by 100 or 200 adds a zero on top of that ( 2 times) multiplying by an odd multiple of 5 with any even number adds a zero. (20 times) 20+2+20=42 This has got to be the ultimate question to life, universe and everything!
  • Try 22.
  • There are going to be PLENTY of factors of two in the result. Each factor of 5 which is multiplied by a factor of 2 makes a factor of ten = a zero on the right. How many factors of 5? There are 20 factors of 5 from 10,20,...,200 Then there are 4 additional factors of 5 from 50,100,150,200 And the next lot would be from 250, 500 but we don't go that high. So that makes 24 zeros. I wish I could think of a way to check this!
