- Anwser:29
8^n=(2^3)^n
44^44=(11*2^2)^44=11^44*2^88
(11^44 *2^88)/ 2^3n
3n=88
n=29

- 44^44/8^n
(11*2^2)^44/(2^3)^n
11^44*2^88/2^3n
Since 2^88is divisible by 2^3n if 88=3n
So n=29 - 11 years agoHelpfull: Yes(6) No(0)
- Ans will be 29

- Anwser:29
8^n=(2^3)^n =2^3n
44^44=(11*2^2)^44=(11^44)*(2^88)
(11^44 * 2^88)/ 2^3n
3n=88
n=29 - 11 years agoHelpfull: Yes(4) No(0)
- Anwser:29
8^n=2^3n
44^44=(11*2^2)^44=11^44*2^88
(11^44 *2^88)/ 2^3n
to divide the no., 2^3n shud completely divide 2^88
