saurav kumar sinha  (12 years ago)

10^m=n*2^2
i.e 10^m=4n
so it only possible in case of integer
if m=2 and n=25
so 25 answer

10^m =n*2^2
or
10^m =4n
n = 10^m/4

Many integer values are possible depending on value of m>1.

saurav if we take m=3 and n=250 then 1000=1000.... so n can be 250 why only 25 ..... hence as dipin says many integers are possible he is right ....reply for this is welcome

clearly frm d relation given,
10^m=n*4
n=(10^m)/4
So m will be such that it is divisible by 4.
therefore value m will be any integer>=2
and for certain values of m=2,3,4...
corresponding values of n will be,n=25,250,2500,...and so on
if u want to solve the series,then u will get "how man solutions are possible"
