to find the numbr of zeroes in this series we need to have look on first two term.As the third term onward is going to be very high.so numbr of zeroes will be given by.4+24^24..as 24^24 gives 6 as its unit digit so number of zeroes in this expression will be 1.

None because (2!)^2! does not have any zero at the end.

ragini dubey  (10 years ago)

none. because (2!)^2+(4!)^4 donot have any zero at the end

1 zero as (2!)^2 + (4!)^4! will have a zero at the last digit.
as last digit of 1st exp is 4 and last digit of 2nd exp is 6.

seetha  (10 years ago)

last digit of 2!^2! = 4
last digit of 4!^4! = 6 so total wud be 10 and 0 is in units place and 1 is carried
now 8!^8! contains 8! zeroes so
somenumber ....................000000000000000000000....00000000+ 10 = .................0000000.....000000010
so at the end it wud be 10
so at the end of the given expresion there wud be only one zero

Is this solution Helpfull? Yes (5) | No (1)  

Kundan Kumar  (10 years ago)

None at the last digit of the expression will be determined by 2!^2! which results into a 4. Hence at the end of expression there will no zero.

Is this solution Helpfull? Yes (4) | No (4)  

Vivek Prajapati  (10 years ago)

0 as 2^2 will yield 4 and hence the unit's digit will b 4

Is this solution Helpfull? Yes (2) | No (2)  

kamal behl  (10 years ago)

no zero bcz 2^2 is 4..nd end digits is not zero

Is this solution Helpfull? Yes (2) | No (1)  

Kunal Verma  (10 years ago)

ca u explain it @amisha ????????

Is this solution Helpfull? Yes (1) | No (1)  

sahithi  (10 years ago)

no zeros is answer

Is this solution Helpfull? Yes | No   

BHANU PRAKASH  (10 years ago)

one zero

2^2 =4

4!^4! = 24^24 ---> 6 is last digit

so 1 zero at last
