- option(1) 25 is the answer
given ,4n=10^m
n=(10^m)/4.
clearly for values of m>1, n is an integer.
for m=2,we have n=100/4=25 - 12 years agoHelpfull: Yes(7) No(2)
- ans =25
exp(m,n)=m^n
exp(10,m)=10^m
exp(2,2) that means n=2 m=2
n*exp(2,2)=n*2^2=4n
now from question exp(10,m)=n*exp(2,2)
10^2=4n
n=1004
n=25.

- according to the question,
10 pow m = 4n;
only with n=25 the values can match
10 pow 2 = 4 * 25;
100 = 100
hence n = 25 - 12 years agoHelpfull: Yes(4) No(2)
- 25. exp(10,2)=25*exp(2,2)
- 12 years agoHelpfull: Yes(1) No(0)
- given
exp(10,m)=4n
if m=1,
10=4(2.5),n=2.5
if m=2
100=4(25),n=25
if m=3
1000=4(250)
hence it is clear that n is a multiple of 25....
so ans is n=25 - 12 years agoHelpfull: Yes(1) No(0)
