prathyusha  (9 years ago)

the number of zeros in the given expression is 9 because number of zeroes depends on how many pairs of (5*2) exists.On expanding the above expression
(5*3)*(2*2*2*2*2)*(5*5)*(11*2)*(2*2*2*5)*(5*5*3)*(7*7*2)*(56*2)*(5*5*5).
A total of 9 pairs exist.Hence,number of zeroes is 9.

Ans : 9
As 5*2 gives 10 . we can get the no of '0' by multiply 5*2 .
// So I will find out the no of 5 and 2 in this Expression .
(5*3)*(2*2*2*2*2)*(5*5)*(11*2)*(2*2*2*5)*(5*5*3)*(7*7*2)*(2*2*2*7*2)*(5*5*5).
= (5*3)*(2^5)*(5^2)*(11*2)*(2^3*5)*(5^2*3)*(7^2*2)*(2^4*7)*(5^3)
= Total no of 5 is 9 = 5^9 and Total no of 2 is 14 = 2^14
=minimum of (9,14)
=9
So Ans : 9
