Solution

The correct option is A 3
The number 5s in 18! $= \frac{18}{5} = 3 a n d i n 19! = \frac{19}{5} = 3$
Therefore, number zeroes in 18! is 3 and in 19! is 3.
Hence, number of zeroes in 18! + 19! = 3 zeroes.

How many zeroes will be there at the end of N = 18! + 19!?

The correct option is A 3The number 5s in 18! =185=3 and in 19!=195=3 Therefore, number zeroes in 18! is 3 and in 19! is 3. Hence, number of zeroes in 18! + 19! = 3 zeroes.

The correct option is A 3
The number 5s in 18! $= \frac{18}{5} = 3 a n d i n 19! = \frac{19}{5} = 3$
Therefore, number zeroes in 18! is 3 and in 19! is 3.
Hence, number of zeroes in 18! + 19! = 3 zeroes.
