Find the number of zeroes in the expression 15*32*25*22*40*75*98*112*125.

• 15=5*3,32=2*2*2*2*2,25=5*5,22=2*11,40=2*2*2*5,75=5*5*3,98=2*7*7,112=2*2*2*2*7,125=5*5*5;
  there are 9 (5*2) pairs so there are 9 zeroes

• 3*5*2^5*5^5*2*11*2^3*5*3*5*5*2*7*7*2^4*7*5^3
  no of zeros= minimum no of (2,5)
  no of zeros=9
• 10 years agoHelpfull: Yes(11) No(5)
• Ans is:9
  There are 9 pairs in following from(2,5)
  3*5,2^5,5^2,2*11,2^3*5,5^2*3,2*29,2^4*7,5^3

• multiply all the unit places of all numbers. then we get 1112424000000000. so number of zeros are 9.

• to do such a question we have to find the no of 10's in the expression. in each & every case finding the no of 5's will be sufficient bcoz each 5 is followed by a 2 thus making it 10. in this expression there are 9 no of zeros by prime factorisation
• 10 years agoHelpfull: Yes(2) No(0)
• multiply all the unit places of all numbers .then we get 400000.so the number of zeros are 5.
• 10 years agoHelpfull: Yes(1) No(2)
• ans 9
  no. of 5's is 9
  so no. of zeroes will be 9

• @ anchal gupta
  compare power of 2's(i.e. 14) and 5's(i.e. 9)
  Minimum of (9,14)
  so 9 is ans.

• @ Jyoti Kothiyal
  Finding no. of 5 is not sufficient
  Exa- 42*75

• take last two nmbers112-2&125-5 thi gives 10 which also gives 0
  like wise 8*5=40which also gives 0
  '' 5*2=10 '' 0
  '' 5*2=10 '' 0
  as 40 consists a zero(0).
  so in TOTAL OF FIVE ZERO'S

• there are 158 wheels in a parking.some are cycles and some are cars....how many cycles are there in parrking??
• 10 years agoHelpfull: Yes(0) No(1)
• ans 9
  total no of 5
  
  
• 10 years agoHelpfull: Yes(0) No(0)
• we get 9 5s then there will be 9 0s
• 10 years agoHelpfull: Yes(0) No(0)
• minimum of(2,5)
  what's mean?
  explain it
• 10 years agoHelpfull: Yes(0) No(0)
• no of zero is 9
  15*32*25*22*40*75*112*125=3*5*2^5*5*2*11*2*4*5*2*5*5*3*7*7*2*2^4*7*5*5*5
  so no of 5=9 and we know 0 is produced multiplication of 2 and 5..
• 10 years agoHelpfull: Yes(0) No(0)
• there are 8 5's
  Hence 8 zeros
• 10 years agoHelpfull: Yes(0) No(0)
• no of zeros will be 9 as
  there are total number of 5 in the given expression is 9.
  on multiplying these with 2,we get 9 zero

• 0, 6, 29, 63,124?
• 10 years agoHelpfull: Yes(0) No(0)
• count the no of 5's by doing the prime factors of above numbers . answere= 9
• 10 years agoHelpfull: Yes(0) No(0)
• (5*3)*(2^5)*5^2*2*11*5*2^3*5^2*3*2*7^2*2^3*7*2*%^3
  total no.of (2*5)pairs is the no.of 10's
• 10 years agoHelpfull: Yes(0) No(1)
• there are total of 9 5's and >9 2's
  so there are total of 9 zeroess

• if 5 * 2 = 10. so one pair of 5 and 2 get one zero. find the no of 5 and 2 pair. so ans is 9
