find zeroes in the expression 15*32*25*22*40*75*98*112*225

• ans= 8
  factorize all the no's and find the no. of pairs of 2*5
  there are 8 pairs
  hence no. of zeroes are 8

• Answer : 9
  Maximum power of 5 in the above expression can be calculated like this. Count all the powers of 5 in the above expression. So number of zeroes are 9.

• 15-->1
  25-->2
  40-->1
  75-->2
  225-->3 no of 5 comes.so total 9

• in the given expression there are 7 number of 2*5 combinations present so number of zeros are 7
• 9 years agoHelpfull: Yes(3) No(2)
• 8 (2,5) combinations are possible

• count total no of 5 coming . so, automatically that will be the answer. answer is 8.

• ans is 8
  factorize the no, in terms of (5*2) where we get (5^8)*(2^14) to get no. of zeros no.of 5 must be multiplied by same no. of 2.

• count the number of zeroes and number divisible by 5,25,125,625 etc so as to form pair with 2 and give a zero...
  Hence, the answer is 8.

• 15*32*25*22*40*75*98*112*225
  (5*3)*32*(5*5)*22*(5*8)*(5*5*3)*98*112*(5*5*9)
  so,the no of 5 generating No o '0's.
  so the answer will be 8

• There are 14pairs of 2 &. 8 pairs of 5.. so obviously it can make 8 zeros...
• 9 years agoHelpfull: Yes(0) No(0)
• ans is 9 as power of 5 is 9
