Question

41.What will be the number of zeroes at the end of the product of 1, 3, 5, 7, ….., 99?​

Answer 1

number of zeros made by 2and 5, hence this a odd number series number of zeros is 0

Answer 2

Answer:

There are no zeroes at the end of the product of zeroes at the end of the product of   $1 , 3 , 5 , 7 , .......99$ .

Step-by-step explanation:

For a number to have zeroes at the end, it must have the factors $2$ and $5$

because $10=2\times5$.

Hence, finding out factors of $5$ and $2$ in the odd  series of  $1 , 3 , 5 , 7 , .......99$  ,

Number of factors of $5$  $= 5,15,25,35,45,55,65,75,85,95$

                     $= 10$  multiples

Number of factors of $2=0$     ....[ Since, series contains odd numbers ]

The minimum among the number of factors of $5$ and $2$ is $0.$

Hence, there are no zeroes at the end of the product of zeroes at the end of the product of   $1 , 3 , 5 , 7 , .......99$ .
